`TITLE OF INVENTION
`
`System and Method for Adapting a USB to Provide Power for
`
`Charging a Mobile Device
`
`FIELD OF INVENTION
`
`This invention relates to rechargeable mobile devices having
`
`access to a Universal Serial Bus (USB).
`
`In particular, this invention
`
`relates to adapting power from the USB for use as a power source by
`
`the charging system of the mobile device to re-charge the portable
`
`power supply of the mobile device.
`
`BACKGROUND OF THE INVENTION
`
` communications bus for connecting a USB host controller such as a
`
`On one
`
`hand,
`
`the Universal Serial Bus
`
`(USB)
`
`is
`
`a
`
`
`
`computer to peripheral devices. USB peripheral devices can be
`
`differentiated based on how they obtain their power in order to
`
`operate while connected. A self-powered peripheral has access to a
`
`power supply external
`
`to USB, whereas a bus-powered peripheral
`
`derives all of its power from the USB.
`
`On the other hand,
`
`traditional mobile devices usually have a
`
`portable power supply that provides power to the mobile device while
`
`it is in service. Some portable power supplies are rechargeable so
`
`that when power is depleted and the portable power supply becomes
`
`discharged, a charging system can be used to restore the charge in
`
`the portable power supply. The charging system obtains power from
`
`an alternate power source, such as an AC outlet of a home or office
`
`electrical network, in order to recharge the portable power supply.
`
`555255-012-132
`
`-2-
`
`Huawei V. FISI Exhibit No. 1003 - 4/59
`
`
`
`Certain rechargeable mobile devices use a separate charging
`
`system such as a docking cradle. Other rechargeable mobile devices
`
`integrate a built-in charging system in order to facilitate recharging
`the portable power supply while it is still installed in the mobile device.
`Recently the hitherto separate fields of USB and mobile devices
`
`have collided. Certain rechargeable mobile devices have evolved to
`
`access USB capabilities in order to become USB peripherals for the
`
`purpose of communicating with USB host controllers such as a
`computer.
`in some cases, USB capabilities have been incorporated
`into the docking cradle, whereas in other cases USB capabilities have
`
`
`
`in a
`been integrated into the rechargeable mobile device itself,
` manner analogous to the location of the traditional charging system.
`Traditional rechargeable mobile devices having a USB already
`
`
`
`have access to two power supplies, specifically a portable power
`
`supply and an alternate power supply. Therefore USB capable
`
`rechargeable mobile devices traditionally operate as self-powered
`
` USB peripherals.
`
`There is a need for a system and method of adapting the
`
`charging system of a USB capable rechargeable mobile device to use
`
`the power traditionally available on the USB as an alternate power
`
`source for recharging the portable power supply of the mobile device
`
`thereby eliminating the need for a separate charging and USB
`
`interfaces.

`
`
`
`BRIEF SUMMARY OF INVENTION
`
`It is an object of the invention to provide a system and method
`
`of adapting the charging system of a USB capable rechargeable
`
`mobile device to use the power traditionally available on the USB as
`
`an alternate power source for recharging the portable power supply of
`
`the mobile device.
`
`Traditionally, the alternate power supply is of a much greater
`
`power capacity than the portable power supply, so that as much
`current as is needed can be drawn from the alternate power supply
`
`by the charging system in order to re-charge the portable power
`
`supply.
`
`
`
`However, power traditionally available on the USB is 100mA to
`
`500mA at 5V, which sometimes has to be shared amongst up to 127
`
`self-powered peripherals. The exact amount of current available
`
`varies as peripherals are connected and disconnected from the USB.
`
` attached to the USB power lines draws current without regard to
`
`In one embodiment of the invention, a charging circuit directly
`
`traditional USB functionality.
`
`In another embodiment of the invention, a charging circuit uses
`
`a current analogous to the current being drawn from the USB on the
`
`Vbus rail. Several elements of the invention are provided by an ASlC
`
`thereby facilitating manufacture.
`
`In yet another embodiment of the invention, the USB interface
`
`accessible to the mobile device isfurther adapted in order to favour
`
`two modes of operation: charging mode and communications mode.
`
`Further features of the invention will be described or will
`
`become apparent in the course of the following detailed description.

`
`DETAILED DESCRIPTION OF THE INVENTION
`
`NON—ENUMERATlNG EMBODlMENT
`
`In one embodiment of the invention, a Li battery is charged by
`
`using the power available at a high-powered USB port, making no
`
`use of the D+ and D- data lines. A charger apparatus, such as a
`
`linear charger based on the LT01734 charge controller,
`
`is used in
`
`this embodiment.
`
`In reference to Figure 1, a USB interface 100 comprising a
`
`Vbus power line 100, D+ data line 120, D- data line 130 and GND
`
`555255-012—132
`
`Huawei V. FISI Exhibit No. 1003 - 7/59
`
`
`
`power line 140 is connected to a charging circuit 400 via the Vbus
`
`110 and GND 140 power lines. A battery 500,
`
`to be charged,
`
`is
`
`connected at it’s positive ent to the charging circuit 400, and at its
`
`negative end to the GND power line 140.
`
`It was determined experimentally that current can be drawn
`
`from several USB ports at a high rate, such as 500mA, without
`
`problem. As used in this description and in the appended claims, a
`
`high-power USB port is a USB port which can provide around 500mA
`
`to be drawn by the invention. Typical means of providing a high-
`
`power USB port are ensuring that the invention is the only USB
`
`device to attach to the USB port of a desktop computer, a laptop
`
` computer, or a self-powered hub.
`
`
`First the charger is attached to the power lines of a high-
`
`powered USB port, such as that of a desktop computer. An open
`
`voltage value is measured on the USB prior to charging operation.
`
`This was about 5.16V in experiments.
`
`Next,
`
`the battery is charged by drawing current at a rate of
`
`around 490mA.
`
`
`
`’k
`
`The start of charge can be detected by observing that the Vbus
`
`voltage value settles to a charging voltage value. This was about
`
`4.76V in experiments.
`
`Finally, when the Vbus reaches its open value,
`
`the end of
`
`charge condition is detected. This was about 5.16V in experiments.
`
`Additionally, when charging from the USB port of a portable
`
`computer, such as a laptop, after charging at the same rate (490mA)
`
`the Vbus voltage value settled to a charging voltage of about 4.65V.
`
`The difference between this laptop charging voltage value and the
`
`555255-012-132
`
`Huawei V. FISI Exhibit No. 1003 - 8/59
`
`
`
`
`
`
`
`Lid;
`ii»
`
`desktop charging voltage value can be used to sense what type of
`
`high-powered device the invention is attached to.
`
`Furthermore, still
`
`in the case of a laptop,
`
`the USB voltage
`
`disappears when the internal
`
`laptop batteries were “completely”
`
`discharged. The voltage is present again immediately after the laptop
`
`is attached to its charger. Therefore, the invention adapts both the
`
`batteries of a laptop and the power adapter of the laptop to provide
`
`power to a rechargeable mobile device via the USB port.
`
`Furthermore, it seems that certain high-power USB ports, such
`
`as a self-powered hub, appear to implement only an over-current
`
`protection,
`
`i.e. they turn off the voltage on the Vbus line for current
`
`values exceeding 700mA-800mA.
`
`Thus a battery charger limiting its charge current value to
`
`500mA can be powered from a high-power USB port without being
`
`necessary to be enumerated by the host, although such a device is
`
`not currently compatible with the current USB standard.
`
`ENUMERATING EMBODIMENT
`
`In another embodiment of the invention,
`
`the USB interface
`
`accessible to the mobile device is further adapted in order to favour
`
`two modes of operation: a charging mode and the traditional
`
`communications mode. The traditional communications mode of
`
`operation of a USB peripheral
`
`is described in great detail
`
`in the
`
`current USB standard and is not discussed presently as it is obvious
`
`to a person skilled in the art. Both modes could be operated
`
`contemporaneously by a skilled person consulting both the standard
`
`and this specification, however this specification will positively set out
`
`and describe the charging mode.
`
`555255-012-132
`
`-7-
`
`Huawei V. FISI Exhibit No. 1003 - 9/59
`
`
`
`In reference to Figures 2, one embodiment of a system used in
`
`the charging mode will be described presently in greater detail.
`
`In
`
`this embodiment,
`
`all
`
`lines of USB interface 100 are utilized.
`
`Specifically, the data D+ 120 and D- 130 lines are utilized to provide
`data communication between a USB controller (not shown) and a
`
`micro processor 200 of the present invention. The microporcessor
`200 selectively controls soft-disconnect signal 120 to cause soft—
`
`disconnect means means 210, such as a pair of electrically controlled
`
`switches to either connect or disconnect the microprocessor from the
`
`USB Interface 100. Microprocessor 200 also communicates with
`
`power level limiting means 300 via set power level signal 220. The
`power level limiting means 300, such as the switched current divider
`
` formed by a plurality of first resistor 330 and switch 340, and a single
`
` second resistor 350, provides a power signal 310, such as a
`
`reference current,
`
`to charging circuit 400. Charging circuit 400 is
`
`connected to power lines Vbus 110 and GND 140, and provides
`
` one end to the charging circuit 400, and at the other to the GND line
`
`power to an attached battery 500 which is electrically connected at
`
`140 of the USB interface.
`
`In charging mode, the mobile device USB interface operates as
`
`a bus—powered peripheral
`
`interface, with a temporary disregard to
`
`communications functionality in favour of obtaining the maximum
`
`amount of current from the USB host controller.
`
`A method of use of the system illustrated in Figure 2 will be
`
`described presently,
`
`in reference to Figure 3. At step 600,
`
`the
`
`microporcessor 200 sets power level signal 220 to a minimum value,
`
`such as 0 mA. At step 610, the microprocessor sets a requested
`
`555255-012-132
`
`-8-
`
`Huawei V. FISI Exhibit No. 1003 - 10/59
`
`
`
`the
`power to a maximum value, such as 500mA. At step 620,
`microprocessor 200 sends soft-disconnect signal 210 so that a
`
`connection to the USB interface is detected by a USB controller,
`
`which was not expressly shown in Figure 2.
`
`At step 630, the microprocessor monitors data lines D+ 120 and
`
`D- 130 and waits for the enumeration process to begin. At step 640,
`
`When connecting, during the enumeration process,
`
`the USB host
`
`controller obtains a power request from the mobile device USB
`
`peripheral interface. However, the USB host controller might not allot
`
`the amount requested, and at Step 650 this is determined.
`
`in order to maximize the likelihood of obtaining a large power
`
`
`
`allotment, the mobile device USB peripheral interface is capable of
`
`electrically disconnecting and reconnecting using switches in order to
`
`force a new enumeration process as if a user had unplugged and
`
`then plugged in the mobile device USB interface to the USB host
`
`controller. This is accomplished by steps 670 and 680 respectively,
`
` after which the method continues at step 620.
`
`
`By comparing the amount of power requested and the amount
`
`of power allotted,
`
`the mobile device USB interface can determine
`
`whether or not to disconnect and attempt a request for less power.
`
`When the amount of power obtained corresponds with the amount of
`
`power allotted,
`
`the USB interface can proceed to operate in
`
`communications mode. This occurs at step 660, after which the
`
`method ends.
`
`In communications mode, one additional element is taught by
`
`the invention over a traditional USB device taught by the standard.
`
`The mobile device USB interface operates as a traditional USB
`
`555255-012-132
`
`-9-
`
`Huawei V. FISI Exhibit No. 1003 - 11/59
`
`
`
`
`
`peripheral interface favouring traditional communications wherein the
`
`mobile device acts as either a self-powered or bus-powered
`
`peripheral, depending on the charge state of the portable power
`
`supply.
`
`If the portable power supply is sufficiently charged,
`
`the
`
`mobile device can act as a self-powered peripheral bypassing the
`
`charging mode. Conversely, if the portable power supply needs to be
`
`recharged, the mobile device can disconnect electrically and act as a
`
`bus-powered peripheral.
`
`CURRENT SENSING EMBODIMENT
`
`In reference to Figures 45, a third embodiment of the present
`
`invention will be described. The Charger Current Sense block 710
`
`provides a signal 717’ to the Charge Control block 732 analogous to
`
`the current being drawn from the USB on the Vbus rail. The Charge
`
`Control block 732 uses this signal 717 to turn on the linear pass
`
`element 727, such as a bipolar transistor,
`
`to a greater or lesser
`
`degree by signal 727 as necessary in order that the total current does
`
`not exceed that required by the system.
`
`In the case of USB, this is
`
`for example either 100mA or 500mA.
`
`In addition and as a parallel
`
`control, the Charge Control block 732 monitors the battery voltage
`
`level via the V_BAT 750 input, and controls the input current via the
`
`linear pass element 720 such that the battery voltage does not
`
`exceed the specified maximum, such as for example 4.20V. The
`
`Charge Control 732 block periodically inhibits delivery of current to
`
`the battery by switching off the linear pass element 720, and briefly
`
`monitoring the battery level at V_BAT 750. This information is used
`
`to determine whether the linear pass element 720 should control
`
`solely the input current, such as monitored by the Charger Current
`
`555255-012—132
`
`-10-
`
`Huawei V. FISI Exhibit No. 1003 - 12/59
`
`
`
`
`
`Sense block 710, or the input current and the battery voltage during
`
`the following “charge on” cycle, which will be described in further
`
`detail in reference to Figure 5 below.
`
`In the absence of input power at the Vbus 110,
`
`the Charge
`
`Control block 732 sets the switch 720 so that the first regulator 736
`
`and second regulator 738 connect to and draw power from the
`
`battery 500 via the V_BAT 750 input.
`
`in order that the microprocessor 740 can monitor and control
`
`the charge system operation,
`
`the actual current delivered to the
`
`battery 500 is monitored by the Cell Current Sense block 760. This
`
`block produces a signal lSENSE__BAT 755 that is analogous to the
`
`actual charge current, and which is converted by an analog-to-digltal
`
`converter, which is not explicitly shown in
`
`the drawing but
`
`is
`
`comprised in Charge Control block 732, and which may be read
`
`serially by the microprocessor on a serial interface, which is also not
`
`shown explicitly in the drawings.
`
`in order to favour manufacturing, a specification for an ASIC
`
`730 to be known as Esker is provided in an appendix. The ASIC
`
`device performs charging, battery monitoring,
`
`low dropout voltage
`
`regulation, system reset control, and integration of a few other power
`
`consuming functions such as proximity sensor, vibrator, and buzzer.
`
`LDOs 736,738 are Low Drop-Out regulators.
`
`An LDO is
`
`typically a linear regulator that can manage to keep its output within
`
`regulation tolerance, while the input falls to only a small amount
`
`above the output voltage. Note that regulator 738 may be a buck
`
`switching regulator external to Esker, as it might need to supply more
`
`current than a linear regulator could handle without overheating.
`
`555255—012—132
`
`_ 1 1-
`
`Huawei V. FISI Exhibit No. 1003 - 13/59
`
`
`
`
`
`In an embodiment using Esker, charge termination will be
`
`performed by the microprocessor, as the charge current will be
`
`monitored.
`
`Note that
`
`the Charge Control block 732 also operates an
`
`electronic switch 727 when voltage is detected at the Vbus input 110.
`
`This switch diverts power as necessary from the source to operate
`
`the regulators 736.738 powering the microprocessor 740,
`
`in order to
`
`ensure that it is possible, even in the case of a severely discharged
`
`lithium battery 500, that the necessary communications and charge
`
`management functions may be performed.
`
`One significant
`
`innovation in the configuration illustrated in
`
`Figure 4 is that the controlled parameter is system input current,
`
`rather than battery charge current. Varying of the battery charge
`
`current is used as the means for controlling (limiting) the system input
`
`current,
`
`thereby compensating for varying power drawn by the
`
`microprocessor.
`
`In
`
`reference to Figure 5, a “periodic charge” and “battery
`
`voltage compensation” method using the system of Figure 4 is
`
`illustrated in great detail. A battery voltage curve 800 and battery
`
`current curve 900 which illustrate the method of charging are
`
`depicted. A constant charge current 910, such as in this example
`
`500mA,
`
`is delivered to the battery until during a constant charge
`
`current period 1000, for instance during the first five constant charge
`
`current cycles 1010A,B,C,D,E in the figure. Between each cycle, the
`
`current
`
`is
`
`stopped 920A,B,C,D,E,F and the
`
`battery voltage
`
`820A,B,C,D,E,F (which climbs during charging) is measured. At the
`
`end of
`
`the constant charge current period 1000,
`
`the voltage

`
`-12-
`
`Huawei V. FISI Exhibit No. 1003 - 14/59
`
`
`
`
`
`820A,B,C,D,E is sampled to be at or above a critical threshold, such
`
`as 4.2V 820F. In the next cycles 1510A,B,C,D, the charge current is
`
`regulated such that the voltage 830 stays approximately constant
`
`during a constant voltage period 1500. When the sampled current
`
`930A,B,C reaches a cirtical
`
`threshold, such as 50mA 930D,
`
`the
`
`charging method finishes. The current is still set to zero between
`
`constant current charging cycles 935A,B,C,D.
`
`This method is illustrated further in Figure 6 with a flowchart. At
`
`step 1020,
`
`the charge current is set to zero. This corresponds to
`
`points 920 of Figure 5. At step 1030, the voltage is sampled 820. At
`
`step 1030, the sampled voltage is compared to a threshold, such as
`
`4.20 V. In the event that the sampled voltage is below the threshold,
`
`at step 1050 a constant current charging cycle as described above in
`
`reference to Figure 5 ensues, aftewhich the method continues at step
`
`1020. However, in the event that the sampled voltage is determined
`
`to be above or equal
`
`to the threhold at step 1030,
`
`the method
`
`continues at step 1520 in constant current charging mode 1500. At
`
`step 1520, a constant current charge cycle, as described above in
`
`reference to Figure 5 ensures. At step 1530,
`
`the current 930 is
`
`sampled. At step 1540, the current 935 is set to zero. At step 1550,
`
`the sampled current 930 is compared to a threshold. in the event that
`
`the current is greater than the threshold,
`
`the method continues at
`
`step 1520.
`
`In the event that the sampled current 930 is below the
`
`threshold, the method ends.
`
`it will be appreciated that
`
`the above description relates to
`
`embodiments by way of example only. Many variations on the
`
`invention will be obvious to those knowledgeable in the field, and
