The MCP7386X family of devices features highly
advanced linear charge management controllers for
use in space-limited, cost-sensitive applications. The
devices combine high-accuracy, constant voltage and
current regulation, cell preconditioning, cell
temperature monitoring, advanced safety timers,
automatic charge termination, internal current sensing,
reverse-blocking protection, charge status and fault
indication in either a space-saving 16-pin 4 x 4 QFN
package, or a 16-pin SOIC package. The MCP7386X
provides a complete, fully functional, stand-alone
charge management solution with a minimum number
of external components.
The MCP73861/3 is intended for applications utilizing
single-cell Lithium-Ion or Lithium-Polymer battery
packs, while the MCP73862/4 is intended for dual
series cell Lithium-Ion or Lithium-Polymer battery
packs. The MCP73861/3 has two selectable
voltage-regulation options available (4.1V and 4.2V),
for use with either coke or graphite anodes and operate
with an input voltage range of 4.5V to 12V. The
MCP73862/4 has two selectable voltage-regulation
options available (8.2V and 8.4V), for use with coke or
graphite anodes, and operate with an input voltage
range of 8.7V to 12V.
The MCP73861/2 and MCP73863/4 differ only in the
function of the charge status output (STAT1) when a
charge cycle has been completed. The MCP73861/2
flashes the output, while the MCP73863/4 turns the
output off. Refer to 

.

The MCP7386X family of devices are fully specified
over the ambient temperature range of -40°C to +85°C.
