DESCRIPTION  
The bq7716xy 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 bq7716xy 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 bq7716xy device provides a Customer Test Mode with greatly reduced  
delay time.
