The MCP7386X series of devices are advanced linear charge management controllers for
space-saving and cost-sensitive applications. The MCP73861 and
MCP73862 integrate many functions into a 16-pin 4 x 4 QFN
package, including high-precision constant voltage, constant current
regulation , battery pre-charge, battery temperature monitoring, advanced safety timer, automatic
charge termination, internal current detection, reverse blocking protection, and charging status and
fault indication. The MCP7386X provides a complete, fully functional
standalone charge management solution that requires very few external components.
The MCP73861 is suitable for
applications , while the MCP73862 is suitable for dual-cell lithium-ion or lithium-polymer battery
applications. The MCP73861 has two optional voltage regulation options (4.1V
and 4.2V) for batteries with carbon anodes or graphite anodes and
operates over an input voltage range of 4.5V to 12V. The MCP73862 also has two selectable
voltage regulation options (8.2V and 8.4V) for use with
batteries with either carbon or graphite anodes, and operates over an input voltage range of 8.7V to 12V.
The MCP7386X family of devices operates over an ambient temperature range of -40°C to
+85°C.
