ADP5063 Linear LiFePO4 Battery Charger with Power Path and USB Compatibility

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.
