It monitors each cell and triggers a fault output when any cell exceeds the 4.55 V threshold, giving the system a hard cutoff before the cell enters an unsafe overcharge condition. ## Package and board-fit — 6-WSON with exposed pad Housed in a 6-WDFN exposed pad package, the BQ294534DRVR's supplier device package is the 6-WSON (2x2 mm). The part operates from -40°C to 110°C ambient, covering the full industrial temperature band.","metaTitle":"Texas Instruments BQ294534DRVR Battery Protection IC","metaDescription":"TI BQ294534DRVR battery protection IC, over-voltage protection for 2-3 Li-ion cells, 6-WSON package, -40 to 110°C, active production, RoHS3.
