Overview

MAX1665S/V/X 19-1605; Rev 0; 1/00 Lithium-Ion Battery Pack Protector General Description The MAX1665 provides protection against overvoltage, undervoltage, overcharge current, and overdischarge current for 2-cell to 4-cell lithium-ion (Li+) battery packs.
Very low operating current ensures that cells are not overdischarged during long storage periods.
The MAX1665 controls two external N-channel MOSFETs to limit the charge and discharge voltages.
Charging is allowed when the per-cell voltage is below +4.
3V.
When the voltage on any cell rises above +4.
3V (overvoltage limit), the MAX1665 turns off the charge MOSFET.
This safety feature prevents overcharge of any cell within the battery pack.
