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

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 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.
