`
`ARGUMENT(S)
`
`Section 2(d) - Likelihood of Confusion
`
`The Examining Attorney has raised as an obstacle to registration of the above-identified Trademark
`Application a potential likelihood of confusion with the mark in U.S. Registration No. 3223582.
`Applicant respectfully requests the Examining Attomey reconsider and withdraw the initial refusal
`based upon the fact that a Consent Agreement between the applicant and owner of Registration No.
`3223582 is imminent.
`
`Substitute Specimen Required
`
`The Examining Attorney has further raised as an obstacle to registration of the above-referenced mark
`the suggestion that the specimen provided is not acceptable to show trademark use in a display
`associated with the goods. Applicant respectfully submits a substitute specimen showing the mark in
`use in commerce as affixed to an instruction manual.
`
`The instruction manual is also commonly known as a datasheet. A datasheet is always sold with
`semiconductor integrated circuits and is necessary for both detennining which integrated circuit is
`appropriate for the circuit in question and for its subsequent implementation into the circuit system.
`
`Conclusion
`
`Applicant believes that the foregoing remarks have sufiiciently addressed the requirements set forth
`by the Examining Attorney and, once the above—referenced Consent Agreement is furnished, place the
`application in condition for registration.

`
`The SMB135 is a programmable single-cell lithium-ion/lithium-polymer
`battery charger for a variety of portable applications. The device
`provides a simple and efficient way to charge high-capacity Li-Ion
`batteries via a USB port or an AC adapter. Unlike conventional
`devices,
`the SMB135’s high-efficiency operation eliminates
`large
`internal temperature rise and lolized hot spot in handheld equipment.
`Summit's proprietary Turbochargem mode allows a 750mA charge
`current from a 500mA USB port.
`resulting to significantly reduced
`charge times.
`
`trickle-charge, pre-charge,
`includes qualification,
`Charge control
`constant current/constant voltage, and termination/safety settings that
`are fully programmable via a serial l2C/SMBus making the device truly
`a flexible solution. Fast charge current level (one or five unit loads)
`can be set via IZC or an input pin (USBSOO/100). An Enable (EN) pin is
`also provided for suspending USB charging and allowing the device to
`work in parallel with AC charger, which may already be integrated into
`a PMIC device.
`In this case, the SMB135 does not allow current to
`flow back to the USB port.
`
`The SMB135 offers a wide variety of features that protect the battery
`pack as well as
`the charger and input circuitry: over-current,
`under/over-voltage and thenrial protection. Ultra-precise, 1% accurate,
`Kelvin-sensed ADOC“‘ technology allows accurate control of battery
`float voltage and improves battery capacity utilization. Status can be
`monitored via the serial port for charge state and fault conditions.
`In
`addition, one LED driver output can be used to signal charge status or
`an under-lover-voltage condition. As a protection mechanism, when
`the junction temperature approaches approximately 110°C, the PWM
`switcher will start to cut back on the duty cycle, to reduce current.
`
`The SMB135 is available in a space-saving 1.3mm x 2.1mm ucsl=“‘
`package with lead-free balls as well as in a lead-free 5x5 QFN-32
`package, and is rated over the -30°C to +85°C temperature range.

`
`
`
`GENERAL DESCRIPTION
`
`The SMB135 is a fully programmable battery charger for
`single-cell Li-Ion and Li-Polymer battery packs. The
`device's high-efficiency, switch-mode operation reduces
`heat dissipation and allows for higher current capability
`for a given package size. The SMB135 provides four
`main charging phases:
`trickle-charge, pre-conditioning
`(pre-charge), constant current and constant voltage.
`The overall system accuracy of the SMB135 is 1%,
`allowing for a higher capacity utilization versus other
`conventional solutions.
`
`When a battery or an external supply is inserted and the
`EN (ENABLE) input is asserted, the SMB135 performs
`the pre-qualification checks before initiating a charging
`cycle. The input voltage needs to be higher than the
`UVLO threshold and the cell temperature needs to be
`within the temperature limits for the charging cycle to
`start. As soon as the input supply is removed,
`the
`SMB135 enters a shutdown mode,
`thereby saving
`battery power. A programmable option also exists that
`allows the user to prevent battery charging until an IZC
`command has been issued.
`
`If the battery voltage is below 2.0V (trickle-charge to pre-
`charge threshold), the device will apply a trickle-charge
`current of 3mA (typical). This allows the SMB135 to
`reset the protection circuit in the battery pack and bring
`the
`battery
`voltage
`to
`a
`higher
`level without
`compromising safety.
`
`Once the battery voltage crosses the 2.0V threshold, the
`SMB135 enters the pre-charge mode.
`This mode
`replenishes deeply depleted cells and minimizes heat
`dissipation during the
`initial
`charge
`cycle.
`The
`preconditioning current is programmable, with the default
`value at C/10.
`if the battery voltage does not reach the
`preconditioning voltage level (programmable) within a
`specified amount of time (pre-charge timeout), the safety
`timer expires and the charge cycle is terminated.
`
`When the battery voltage reaches the pre-charge to fast-
`charge voltage level, the SMB135 enters the constant
`current (fast charge) mode. The fast charge current
`level is programmable in two ways: a) via an external
`sense resistor and b) via the corresponding register.
`
`SMB135
`
`Prelim/nary Datasheet
`
`Once the final float voltage (programmable) has been
`reached, the battery charger will enter a constant voltage
`mode in which the battery voltage is kept constant,
`allowing the charge current to gradually taper off. The
`constant-voltage charging mode will continue until the
`charge current drops below the termination current
`threshold, or until the fast charge timer has expires. The
`termination current
`threshold is programmable from
`25mA to 130mA in 15mA increments.
`
`the SMB135
`After the charge cycle has terminated,
`If the battery
`continues to monitor the battery voltage.
`voltage falls below the recharge threshold (typically
`115mV below float
`voltage),
`the
`SMB135
`can
`automatically top-off the battery.
`
`A wide range of protection features is also included in
`the SMB135. These include input and output over-
`voltage protection, battery missing detector and thermal
`monitor for continuous cell temperature monitoring and
`pre-qualification.
`
`The following charging parameters can be adjusted
`dynamically via the |2C interface, for optimizing battery
`management real-time. These parameters can also be
`programmed statically via a user-friendly GUI interface:
`
`Battery (float) voltage
`Fast charge current
`Pre-conditioning voltage threshold
`Pre-conditioning charge current
`Termination current
`
`Safety charge timers
`Temperature window
`
`The SMB135 also offers three programmable PWM
`switching frequencies ranging from 750kHz to 1250kHz
`in 250kHz increments.

`Note 1: The ACTUAL charging current always equals the nominal values given in the register tables minus Ioppsgr, where Io;,=5Er is the device's total
`active current. The 525mA nominal value shown here is with the hex value F in register h00[7:4]. For USB1, the nominal value is the lower of the one
`selected in the register and 100mA.
`Note 2: Voltage, current and frequency accuracies are only guaranteed for factory-programmed settings. Changing any of these parameters from the
`values reflected in the customer specific CSIR code will result in inaccuracies exceeding those specified above.
`Note 3: The SMB135 device is not intended to function as a battery pack protector. Battery packs used in conjunction with this device need to provide
`adequate internal protection and to comply with the corresponding battery pack specifications.

`
` SMB135
`
`APPLICATIONS INFORMATION
`DEVICE OPERATION
`
`The SMB135 is a fully programmable battery charger
`for single-cell Li-lon and Li-Polymer battery packs. The
`device’s
`high-efficiency,
`switch-mode
`operation
`reduces heat dissipation and allows for higher current
`capability for a given package size.
`The SMB135
`provides four main charging phases:
`trickle-charge,
`pre-conditioning (pre-charge), constant
`(fast-charge)
`current and constant voltage.
`The overall system
`accuracy of the SMB135 is 1%, allowing for a higher
`capacity utilization versus other conventional solutions.
`Furthermore, the main battery charging parameters are
`programmable, allowing for high design flexibility and
`sophisticated battery management.
`Power Supply
`
`The SMB135 can be powered from an input voltage
`between +4.35 and +6.5 Volts applied between the IN
`pin and ground. The voltage on the IN pin is monitored
`by Under~Voltage (UVLO) and Over-Voltage Lockout
`(OVLO) circuits, which prevent the charger from turning
`on when the voltage at this node is less than the UVLO
`threshold (+3.5V), or greater than the OVLO threshold
`(+7.0V). The IN pin also supplies an internal +2.5V
`VDD regulator,
`filtered
`by an external
`capacitor
`attached between the VDDCAP pin and ground; this
`filtered voltage is then used as an internal VDD supply.
`When the input supply is removed, the SMB135 enters
`a low-power shutdown mode, exhibiting a very low
`discharge leakage current
`(2uA),
`thereby extending
`battery life.
`Pre-qualification Mode
`When an external wall adaptor or a USB cable is
`connected,
`the SMB135 performs a series of pre-
`qualification tests before initiating the first charge cycle.
`The input voltage level needs to be higher than the
`UVLO threshold,
`
