Product details

Over-voltage watchdog for 2-3 Li-ion stacks

The Texas Instruments BQ294534DRVR is a dedicated over-voltage protection IC for 2-3 series lithium-ion battery packs. 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.

Frequently asked questions

What is the closest functional second-source to BQ294534DRVR?

The BQ296217DSGT is a close peer — also a battery protection IC from TI, handling 2-4 cells with over-voltage fault protection in a similar temperature range. However, the BQ296217DSGT supports up to 4 cells versus the BQ294534DRVR's 2-3 cells, and it comes in a different package (DSGT vs DRVR). Confirm the cell count and footprint before substituting.
