FUNCTION
Voltage Reference Output 1.24V, 10mA max. Do not short circuit
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 volage on pin 2 is lower
than 0.8V
Current Limitation Reference Input
Ground
Current Limitation Loop Input, connected to the sense resistor
Output pin common to the voltage regulation and current limitation loops. This
output can drive the primary side (LED) of an optocoupler
Voltage Regulation Loop Input
Power Supply Input (4.5 ~ 32VDC)
