GENERAL DESCRIPTION

The ADP5063 charger is fully compliant with USB 3.0 and the USB Battery Charging 1.2 Compliance Plan Specification, and enables charging via the mini USB VBUS pin from a wall charger, car charger, or USB host port.

The ADP5063 operates from a 4 V to 6.7 V input voltage range but is tolerant of voltages up to 20 V, thereby alleviating concerns about USB bus spikes during disconnection or connection scenarios.
