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. 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.
