The bq7718xy family of products provides an overvoltage monitor and protector for Li-Ion
battery pack systems. Each cell is monitored independently for an overvoltage condition. For
quicker production-line testing, the bq7718xy device provides a Customer Test Mode (CTM) with
greatly reduced delay time.
In the bq7718xy device, an internal delay timer is initiated upon detection of an
overvoltage condition on any cell. Upon expiration of the delay timer, the output is triggered into
its active state (either high or low depending on the configuration).
