PRODUCTION DATA
The BQ2945xy devices are second-level protectors used for overvoltage protection for the battery pack in the application. The device, when configuring the OUT pin with active high, drives an NMOS FET that connects the fuse to ground in the event of a fault condition. This provides a shorted path to use the battery or charger power to blow the fuse and cut the power path.
