Pin Description

Pin No.

Pin Name

Function

7

DI

The serial data input pin which used to receive 8-bit wide serial data

6

CK

The shift clock input pin which input signal from DI pin to 8-bit shift register by the rising

edge of clock signal

8

CS

When this pin is "Low", DI pin can receive the data into the 8-bit shift register.

The each bit will be latched at rising edge of the clock signal

15

The output pin of the amplified A/D data

11

ADJ

The voltage output pin for adjusting A/D reference voltage

10

REF IN

The reference voltage input pin of the A/D converter

19

IN1

The A/D converter input pin

18

IN2

The A/D converter input pin

17

IN3

The A/D converter input pin

16

IN4

The A/D converter input pin

20

The charge current sense input pin for high side voltage

21

The charge current sense input pin for low side voltage

13

The discharge current sense input pin for high side voltage

14

The discharge current sense input pin for low side voltage

9

DCDOUT

The discharge current detect circuit output pin

23

The voltage detection input pin

22

The current detection input pin

24

This pin is used to make connection with capacitor and resistor which are used for phase

compensation

1

SW

The pre-drive pin which used to connect the external Pch Tr

3

OSC

The pin used to connect capacitor to determine the frequency of oscillator

5

PS

12

The power supply pin

4

GND

The ground pin

2

The ground pin of power unit
