Pin Functions

PIN I/O DESCRIPTION
NAME NO.
BAT 5, 6 I/O Battery input and output.
CE 9 I Chip enable input (active high)
DPPM 13 I Dynamic power-path management set point (account for scale factor)
GND 19, 20 I Ground input
IN 4 I Charge input voltage
ISET1 10 I/O Charge current set point and precharge and termination set point
ISET2 7 I Charge current set point for USB port. (High = 500 mA, Low = 100 mA) See half-charge current mode using ISET2.
MODE 8 I Power source selection input (Low for USB mode current limit)
OUT 15, 16, 17 O Output terminal to the system
PG 18 O Power-good status output (open-drain)
STAT1 2 O Charge status output 1 (open-drain)
STAT2 3 O Charge status output 2 (open-drain)
TMR 14 I/O Timer program input programmed by resistor. Disable fast-charge safety timer and termination by tying TMR to VREF.
TS 12 I/O Temperature sense input
VREF 1 O Internal reference signal
VSS 11 – Ground input (the thermal pad on the underside of the package) There is an internal electrical connection between the exposed thermal pad and VSS pin of the device. The exposed thermal pad must be connected to the same potential as the VSS pin on the printed-circuit board. Do not use the thermal pad as the primary ground input for the device. VSS pin must be connected to ground at all times.
