ADP5063ACPZ-1-R7 (ANALOG DEVICES)

The ADP5063ACPZ-1-R7 is a linear LiFePO4 Battery Charger with power path and USB compatibility. It operates from a 4 to 6.7V input voltage range but is tolerant of voltages up to 20V, 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 an USB power supply. Based on the type of USB source, which is detected by an external USB detection chip, it can be set to apply the correct current limit for optimal charging and USB compliance. It has three factory-programmable digital input/output pins that provide maximum flexibility for different systems.
