Pin

Type

Function

1

OUTPUT

Voltage Reference Output 1.24V, 10mA max. Do not short circuit

7

INPUT

Voltage Regulation Loop input

5

INPUT

Current Limitation Loop Input, connected to the sense resisto

3

INPUT

Current Limitation Reference Input

2

INPUT

Current source enable input. This current source can be used to offset the

voltage measurement on the sense resistor and therefore to modify the

charge current. The current source enabled when the input voltage on pin 2

is lower than 0.8V.

OUTPUT

6

OUTPUT

Output pin common to the voltage regulation and current limitation loops.

This output can drive the primary side (LED) of an optocoupler.

8

INPUT

Power Supply Input (4.5 to 32V DC)

GND

4

INPUT

Ground
