Description
The MCP7386X family of devices are highly advanced
linear charge management controllers for use in space-
limited, cost-sensitive applications. The MCP73861 and
MCP73862 combine high-accuracy constant voltage,
constant current regulation, cell preconditioning, cell
temperature monitoring, advanced safety timers, auto-
matic charge termination, internal current sensing,
reverse-blocking protection, and charge status and fault
indication in a space-saving 16-pin, 4 x 4 QFN package.
The MCP7386X provides a complete, fully-functional,
stand-alone charge management solution with a
minimum number of external components.
The MCP73861 is targeted for applicatioins utilizing
single-cell Lithium-Ion or Lithium-Polymer battery
packs, while the MCP73862 is targeted for dual series
cell Lithium-Ion or Lithium-Polymer battery packs. The
MCP73861 has two selectable voltage-regulation
options available (4.1V and 4.2V), for use with either
coke or graphite anodes, and operates with an input
voltage range of 4.5V to 12V. The MCP73862 has two
selectable voltage-regulation options available (8.2V
and 8.4V), for use with coke or graphite anodes, and
operates with an input voltage range of 8.7V to 12V.
The MCP7386X family of devices are fully specified
over the ambient temperature range of -40°C to +85°C.
