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.
