DESCRIPTION
Dynamic power-path management set point (account for scale factor)
Charge current set point for AC input and precharge and termination set point for both AC and USB
Charge current set point for USB port. (High = 500 mA, Low = 100 mA)
3.3-V LDO regulator
Output terminal to the system
AC or USB power-good status output (open-drain)
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 programmed by resistor. Disable safety timer and termination by tying TMR to LDO.
Temperature sense input
USB charge input voltage
USB power-good status output (open-drain)
Battery charge voltage selection
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.
