Power source selection input (low for USB, High for AC)
Charge status output 1 (open-drain)
Charge status output 2 (open-drain)
Timer program input
Temperature sense input
USB charge input voltage
USB powergood status output (open-drain)
Ground input (the thermal pad on the underside of the package) There is an internal electrical connection
between the exposed thermal pad and VSS pin of the device. The exposed thermal pad must be
connected to the same potential as the VSS pin on the printed circuit board. Do not use the thermal pad
as the primary ground input for the device. VSS pin must be connected to ground at all times.
