MCP73831T 2ACI/OT Microchip Charger IC

Description

GENERAL DESCRIPTION
The MCP73831/2 devices are highly advanced linear charge management controllers for space-limited, cost-sensitive applications. The MCP73831/2 is available in an 8-Lead, 2 mm x 3 mm DFN package or a 5-Lead, SOT-23 package. Besides their small physical size, the low number of external components required make the MCP73831/2 ideally suited for portable applications. For applications charging from a USB port, the MCP73831/2 adheres to all the specifications governing the USB power bus.
