Description
set to 1 if charger is detected
Set to 1 if charger is active
Set to 1 if overvoltage on pin VCHARGER is applied
Charger Detection:
The Charger will be detected by comparison of the V_USB voltage with the Vsupply voltage.
If V_USB is 50mV higher than VSupply voltage or V_USB > 4.3V or the USB_ChDet is set to 1.
