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.

The ADP5063 features an internal field effect transistor (FET)

between the linear charger output and the battery. This permits

battery isolation and, therefore, system powering under a dead

battery or no battery scenario, which allows immediate system

function upon connection to a USB power supply.

Based on the type of USB source, which is detected by an external

USB detection chip, the ADP5063 can be set to apply the correct

current limit for optimal charging and USB compliance.

The ADP5063 has three factory-programmable digital input/out-

put pins that provide maximum flexibility for different systems.

These digital input/output pins permit a combination of features,

such as input current limits, charging enable and disable, charging

current limits, and a dedicated interrupt output pin.
