Fun ction

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 resistor

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 is 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.
