APPLICATION NOTE
POWER STATUS INDICATORS
The STAT pin is designed to source or sink current.
LEDs can be configured to indicate charging or battery full.
The battery full indicator can be connected to DC OK
rather than GND to insure it is off when the input power is
removed and the STAT pin and DC OK pin go to a high
impedance state.
