It monitors each cell voltage independently and triggers a fault output when any cell exceeds the over-voltage threshold, acting as a safety backup to the primary fuel-gauge or charger IC. Housed in an 8-WDFN exposed pad package (supplier device package 8-WSON 3x4 mm), the part is surface-mount and requires a thermal pad on the PCB for heat dissipation.","metaTitle":"BQ771604DPJR Texas Instruments Battery Protection IC","metaDescription":"Texas Instruments BQ771604DPJR Li-Ion battery protection IC, 2-4 cells, over-voltage protection, -40°C to 110°C, 8-WSON package.
