Product details

Over-voltage watchdog for 2–4 cell Li-ion packs

The Texas Instruments BQ296112DSGT is a dedicated battery protection IC for lithium-ion packs of 2 to 4 series cells. Its sole fault-protection function is over-voltage monitoring — it pulls the discharge FET gate low when any cell exceeds the factory-set threshold. There is no integrated over-current, short-circuit, or over-temperature detection; those must be handled by an external gauge or separate protector. The device operates across -40°C to 110°C, covering industrial and automotive cabin environments.

Package and footprint — 8-WSON (2x2 mm)

The supplier device package is 8-WSON measuring 2x2 mm. Tape & Reel and Cut Tape options are available.

Frequently asked questions

Is BQ296112DSGT compatible with 4-cell batteries?

Yes. The BQ296112DSGT supports 2 to 4 series cells, so a 4-cell (14.8 V nominal) Li-ion pack is within its rated range.

What is the BQ296112DSGT used for?

It is a battery protection IC that monitors the voltage of each cell in a 2- to 4-cell Li-ion series stack and triggers a discharge FET shutoff if any cell exceeds the over-voltage threshold.
