Pin Description

1

VPS

Analog Input Voltage position sense. Power supply output voltage information to be

compared with the internal reference voltage.

2

DRV

Analog

Output

External circuit drive. It drives an external circuit such as the opto-

coupler LED.

3

PLRIN

Power Input Pulse linear regulator (PLR) input. Connect this pin through a diode

(cathode to the pin) to the drain of the synchronous rectifier MOSFET.

4

DRAIN

Analog Input Synchronous rectifier MOSFET drain voltage sensing.

5

OUT

Output

Synchronous rectifier MOSFET driver.

6

GND

Ground

Ground.

7

Power Input

Output of internal LDO and PLR. It provides bias voltage for the

internal logic circuit and the MOSFET driver. Connect this pin to a

capacitor.

8

Power Input

Connect to adapter/charger output for bias voltage. The internal LDO

for the PLR enable comparator and the SR enable comparator.
