ATA6871 Description
The ATA6871 is a battery cell monitoring circuit designed to act as an emergency, safety, or backup circuit in Li-ion battery systems for electrical and hybrid electrical vehicles (EV/HEV). It monitors overvoltage, undervoltage, and the cell temperature in Li-ion batteries without the need of a microcontroller. The circuit has an advanced self-test functionality, which checks the proper functionality of the...
