Pin Assignment

Pin Description

2 TS

External NTC Thermistor Input. Connect the TS input to the NTC thermistor in the

battery pack. TS monitors a 10k ? NTC thermistor. For applications that do not utilize

the TS function, connect a 10k ? fixed resistor from TS to PVSS to maintain a valid

voltage level on TS.

3 LOWBAT#

Low Battery Indication Output. LOWBAT# pulls to PVSS when low voltage level of

battery is detected. Connect LOWBAT# to the desired logic voltage rail. 4 BOOST_ON#

Boost On output . BOOST_ON# pulls to PVSS when boost is turned on. Connect

BOOST_ON# to the desired logic voltage rail. 5 FLASHLIGHT# Flashlight output. FLASHLIGHT# pulls to PVSS when flashlight function is turned on.

Connect FLASHLIGHT# with a pull-up resistor. The pull-up resistor value decides

flashlight sink current. 6 PVSS Power Ground. Connect to the thermal pad and to the ground rail of the circuit.

DESCRIPTION

7 LX Boost Converter Output 8 NC

No connection. 9 BOOST_OUT BOOST_OUT Input . Connect this input pin from BAT signal. 10 FB Feedback input for Boost.

11 BUTTON Button input . Push button function to turn on/off boost or flashlight.

12 BLED0#

Battery Capacity Indicator LED0 output . BLED0# pulls to PVSS when the internal comparator voltage is reached. Connect BLED0# to the desired logic voltage rail. 13 BLED1#

Battery Capacity Indicator LED1 output . BLED1# pulls to PVSS when the internal

comparator voltage is reached. Connect BLED1# to the desired logic voltage rail. 14 BAT Charger Power Stage Output and Battery Voltage Sense Input. Connect BAT to

the positive terminal of the battery. Bypass BAT to PVSS with a 4.7μF to 47μF ceramic

capacitor. 15 IN Input Power Connection. Connect IN to the external DC supply (AC adapter or USB

port). The input operating range is 4.35V to 5.5V. Connect bypass capacitor 22uF to

32uF to PVSS. 16 BLED2#

Battery Capacity Indicator LED2 output . BLED2# pulls to PVSS when the internal

comparator voltage is reached. Connect BLED2# to the desired logic voltage rail.

17 AVSS

There is an internal electrical connection between the exposed thermal pad and the AVSS pin of

the device. The thermal pad must be connected to the same potential as the AVSS pin on the printed circuit board. Do not use the thermal pad as the primary ground input for the device. AVSS pin must be connected to ground at all times.
