12-Channel, High-Voltage Battery-Pack Fault Monitors
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. The undervoltage level is also user selectable from +1.6V to +2.8V in 200mV increments. These levels are guaranteed to ±100mV over the entire temperature range. Undervoltage detection can be disabled as one of the user-configuration options.
The MAX11080/MAX11081 have a built-in level-shifter that allows up to 31 MAX11080/MAX11081 devices to be connected in a daisy-chain fashion to reduce .
