Pin Function Descrition

Output pin for charging control. An external photocoupler is drived from

the output for constant voltage and constant current charging control.

Reference input for current amplifier.

Charging current sensing input . It is connected to a sense resistor

(system ground)

Ground

Charging current monitoring output. This pin is connected to a micro

controller and detects the amplified voltge derived from CS pin.

Reference current control input. The Amplifier reference current is

controlled according to the resistor which is connected to the pin IREF.

Voltage sensing input for constant battery voltage control. It is normally

connected to the battery charger output through a resistor divider.

Power supply input. The typical operating voltage range is 2.5V to 16V.
