Note 1: The supply voltage (VDD) = VAC when input power source is from Ac-Adapter and the supply voltage (VDD) = VUSB
when input power source is from USB-Port.
2: The value is guaranteed by design and not production tested.
3: The current is based on the ratio of selected current regulation (IREG).
4: The maximum charge impedance has to be less than shutdown impedance for normal operation.
