DESCRIPTION

The bq2947xy family of products is an overvoltage monitor and protector for Li-Ion battery pack systems. Each

cell is monitored independently for an overvoltage condition.

In the bq2947xy device, an external 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). The external delay timer feature also includes the ability to detect an open or shorted delay

capacitor on the CD pin, which will similarly trigger the output driver in an overvoltage condition.

For quicker production-line testing, the bq2947xy device provides a Customer Test Mode with reduced delay

time.
