MCP73853/MCP73855 pdf datashee

The MCP7385X devices are highly advanced linear
charge management controllers for use in spacelimited,
cost-sensitive applications. The MCP73853
combines high-accuracy constant-voltage, constantcurrent
regulation, cell preconditioning, cell temperature
monitoring, advanced safety timers, automatic charge
termination, internal current sensing, reverse blocking
protection and charge status and fault indication in a
space-saving 16-lead, 4 x 4 QFN package.
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 x 3 DFN package.
The MCP73853 and MCP73855 are 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.
The MCP7385X devices provide complete, fullyfunctional,
charge management solutions, operating
with an input voltage range of 4.5V to 5.5V.
The MCP7385X devices are fully specified over the
ambient temperature range of -40°C to +85°C.
