The MCP7385X devices are highly-advanced, linear charge management controllers, for use in spacelimited, cost-sensitive applications. The MCP73855 employs all the features of the MCP73853, with the exception of the cell temperature monitor and one status output. The MCP73855 is offered in a space-saving 10-lead, 3×3 DFN package. The MCP73855 is designed specifically for USB applications, adhering to all the specifications governing the USB power bus. The MCP7385X devices provide two selectable voltage regulation options (4.1V or 4.2V) for use with either coke or graphite anodes. These devices have complete and fully-functional, charge management solutions, operating with an input voltage range of 4.5V to 5.5V. These are fully specified over the ambient temperature range of -40°C to +85°C.
