PRODUCTION DATA
The BQ2946xx devices are a family of second-level protectors used for overvoltage protection of the single-cell battery pack in the application. The OUT pin drives a NMOS FET that connects the fuse to ground in the event of a fault condition. This provides a shorted path to use the battery and/or charger power to blow the fuse and cut the power path.
