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 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 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.
Applications
Lithium-Ion/Lithium-Polymer Battery Chargers
Personal Data Assistants (PDAs)
Cellular Telephones
