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
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 bat-
tery power conservation. The MAX1666 can operate in a
stand-alone configuration or in conjunction with a micro-
controller. It is available in three versions: the “S” version
monitors two Li-Ion cells, the “V” version monitors three
cells, and the “X” version monitors four cells.
