3 Description
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 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.
