PRODUCTION DATA
The BQ2946xx is a second-level overvoltage (OV) protector for a single cell. The cell voltage is compared to a protection voltage threshold, VOV. The protection threshold is preprogrammed at the factory with a range from 3.85 V to 4.65 V. When the OVP is triggered, the OUT pin goes high to activate an external N-channel FET, which conducts a low-impedance path to blow a fuse.
