TERMINAL FUNCTIONS

TERMINAL

I/O DESCRIPTION

NAME NO.

AC 5 I Charge input voltage from AC adapter

BAT/OUT 16 I/O Charge current output

BAT/OUT 17 I Battery input to DC-DC converter

CE 15 I Charge enable input (active low)

EN 4 I Enable input for DC-DC converter (active high)

FB 2 I Feedback pin for DC-DC converter

PWM control input for the DC-DC converter. A high on FPWM = forced PWM mode. A low = power save

FPWM 20 I

mode.

ISET1 12 I Charge current set point for AC input and precharge and taper set point for both AC and USB

ISET2 13 I Charge current set point for USB port (High = 500 mA, Low = 100 mA, High-Z = disable USB charge)

NC 1, 10, 11 – No connect. These pins must be left floating.

PG 14 O Power good status output (active low)

STAT1 7 O Charge status output 1 (open-drain)

STAT2 8 O Charge status output 2 (open-drain)

SW 19 O Phase node of the DC-DC converter

USB 6 I Charge input voltage from USB adapter

Ground Input. Also note that there is an internal electrical connection between the exposed thermal pad

and VSS pins of the device. The exposed thermal pad must be connected to the same potential as the

VSS 3, 9, 18 –

Vss pin on the printed circuit board. Do not use the thermal pad as the primary ground input for the

device. All VSS pins must be connected to ground at all times.
