DESCRIPTION
NO.
Charger input voltage from ac adapter. The AC pin can be left open or can be connected to
ground if the charger is not used.
Charger input voltage from USB port. The USB pin can be left open or can be connected to
ground if the charger is not used.
External charge current setting resistor connection for use with ac adapter
Sense input for the battery voltage. Connect directly with the battery.
Power output of the battery charger. Connect directly with the battery.
Battery temperature sense input
Indicates when a valid power supply is present for the charger (open drain)
