bq771600 Overvoltage Protection

The bq7716xy device family 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 bq7716xy device provides a Customer Test Mode with greatly reduced delay time. In the bq7716xy device, an external delay timer is initiated upon d.
