MCP73831/2 Charge Management Controllers

Microchip MCP73831/2 Charge Management Controllers have high accuracy and are for use in space-limited, cost-sensitive applications. The MCP73831/2 are housed in 8-Lead, 2x3mm DFN packages or 5-lead, SOT-23 packages. The MCP73831/2 is ideally suited for portable applications with a low number of external components required. The controllers adhere to all the specifications governing the USB power bus for applications charging from a USB port.
