General Description

The MAX11080/MAX11081 are battery-pack fault-monitor ICs capable of monitoring up to 12 lithium-ion (Li+) battery cells.

This device is designed to provide an overvoltage or undervoltage fault indication when any of the cells cross the user-selectable threshold for longer than the set program-delay interval.

The overvoltage levels are pin selectable from +3.3V to +4.8V in 100mV increments, and have a guaranteed accuracy of ±25mV over the entire temperature range.
