MAX11081 Datasheet High-voltage Battery-pack Fault Monitor

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: MAX11080/MAX11081 19-4584; Rev 1; 6/10 EVAALVUAAILTAIOBNLEKIT 12-Channel, High-Voltage Battery-Pack Fault Monitors.

This datasheet includes multiple variants, all published together in a single manufacturer document.

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.

Key Features
