Product details

Single-cell Li-ion protector with three-axis fault detection

The Texas Instruments BQ24305DSGT is a battery protection IC designed for single-cell Lithium Ion packs. It monitors the cell for over-current, over-temperature, and over/under-voltage conditions and disconnects the load or charger when a fault is detected.

Temperature range — 0°C lower limit is a selection gate

Operating temperature is rated 0°C to 125°C (junction). The 0°C floor means this part is not suited for battery packs that see below-freezing ambient — cold-crank automotive, outdoor IoT nodes in winter, or refrigeration equipment. For sub-zero designs, look for a part with an extended industrial or automotive temperature grade.

Frequently asked questions

Does BQ24305DSGT support overvoltage protection?

Yes. The BQ24305DSGT includes over/under-voltage protection as part of its fault protection set, along with over-current and over-temperature detection.

Is BQ24305DSGT a direct replacement for BQ24305DSGR?

The BQ24305DSGT and BQ24305DSGR share the same base product number BQ24305 and the same 8-WSON (2x2) package. The difference is the packaging medium — DSGT is Tape & Reel, DSGR is typically Cut Tape. Electrically they are identical; the reel variant is the production-volume option.
