GENERAL DESCRIPTION

The ADP5061 charger is fully compliant with USB 3.0 and the USB Battery Charging Specification 1.2 and enables charging via the mini USB VBUS pin from a wall charger, car charger, or USB host port.

The ADP5061 operates from a 4 V to 6.7 V input voltage range but is tolerant of voltages up to 20 V. The 20 V voltage tolerance alleviates the concerns about the USB bus spiking during disconnect or connect scenarios.

The ADP5061 features an internal FET between the linear charger output and the battery. This permits battery isolation and, hence, system powering under a dead battery or no battery scenario, which allows for immediate system function on connection to a USB power supply.
