Advanced Lithium-Ion
Battery-Pack Protector
General Description
The MAX1666 provides complete protection against over-
voltage, undervoltage, overcharge current, overdischarge
current, and cell mismatch for 2-cell to 4-cell lithium-ion
(Li+) battery packs. The voltage of each cell in the battery
pack is checked and compared to the programmable
threshold and to the other cells in the pack.
The MAX1666 protects the battery pack in an overcurrent
condition by disconnecting the pack from the load at a pro-
grammable limit. On-chip power MOSFET drivers control
external P-channel MOSFETs to disconnect the cells from
external terminals when faults occur.
The MAX1666 employs a unique timing scheme that
allows three modes of operation for optimal performance
and battery power conservation. The MAX1666 can oper-
ate in a stand-alone configuration or in conjunction with a
microcontroller. It is available in four versions: the S ver-
sion monitors two Li+ cells, the A and V versions monitor
three cells, and the X version monitors four cells. When
the charge path is disabled by the charge control pin, the
MAX1666A reduces current consumption compared to
the MAX1666S/V/X.
