Description

The MCP7386X family of devices are 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 or 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 have 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

have

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 only difference between the MCP73861/2 and

MCP73863/4, respectively, is the function of the charge

status output (STAT1) when a charge cycle has been

completed. The MCP73861/2 flash the output, while

the MCP73863/4 turn the output off. Refer to

Section 5.2.1 “Charge Status Outputs (STAT1,

STAT2)”.

The MCP7386X family of devices are fully specified

over the ambient temperature range of -40°C to +85°C.
