bq2969 Overvoltage Protector

Texas Instruments bq2969 Overvoltage Protector is a high-accuracy, low-power overvoltage protector with a 3mA regulated output supply for Li-ion and LiFePO4 (LFP) battery pack applications. Each cell in a 2-series to 4-series cell stack is individually monitored for an overvoltage condition. Upon detection of an overvoltage condition on any cell, an internally fixed delay timer is initiated. Upon expiration of the delay timer, the output pin is triggered into an active state to indicate that an overvoltage condition has occurred.
