MCP73837 - Microchip Technology

MCP73837 (MCP73837 / MCP73838) Advanced Stand-Alone Li-Ion / Li-Polymer Battery Charge Management Controller

The MCP73837 and MCP73838 devices are fully integrated linear Li-Ion / Li-Polymer battery chargers with autonomous power source selection. Along with its small physical size, the low number of external components required makes the MCP73837/8 ideally suitable for portable applications. The MCP73837/8 automatically selects the USB-Port or AC-Adapter as the po.
