Description

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 tempera-

ture 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 manage-

ment 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.

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
