BQ294522 Overvoltage Protection

The BQ2945xy family of products is a secondary-level voltage monitor and protector for Li-ion battery pack systems. Each cell is monitored independently for an overvoltage condition. Based on the configuration, an output is triggered after a fixed delay if any of the two or three cells has an overv.

BQ294522 Features

* 2-series and 3-series cell overvoltage monitor for secondary protection

* Fixed programmable delay timer

* Fixed OVP threshold

* Available range from 3.85 V to 4.6 V

* Fixed OVP delay option: 4 s or 6.5 s

* High-accuracy overvoltage protection: ±10 m
