MCP73853
The MCP73853 is a highly advanced linear charge management controller for use in space limited, high-performance applications. The MCP73853 integrates most of the external components (pass transistor, reverse blocking protection, current sensing) and combines high-accuracy constant voltage, constant current regulation, cell preconditioning, cell temperature monitoring, advanced safety timers, automatic charge termination, and charge status and fault indication in a space-saving 16-pin, 4 x 4 QFN package.
The MCP73853 is designed specifically for USB applications, adhering to all the specifications governing the USB power bus.
