BQ2961 Datasheet (Texas Instruments) - Overvoltage Protection

BQ2961, Overvoltage Protection

The BQ296xxx family is a high-accuracy, low-power overvoltage protector with a 2-mA regulated output supply for Li-Ion battery pack applications.

Each cell in a 2-series to 4-series cell stack is individually monitored for an overvoltage condition.

An internally fixed-delay timer is initiated upon d
