Product details

What this protection IC covers and where it fits

The Texas Instruments BQ24308DSGT is a Li-Ion battery protection IC that monitors for over/under voltage, over current, and over temperature faults, shutting down the output when any threshold is crossed.

Fault protection coverage and BOM fit

Because the protection thresholds are fixed internally, there is no external resistor-divider to trim — the BOM stays tight, but the trip points are not adjustable after the board is stuffed.

No stock-holding claim; each lot is verified before shipment.

Frequently asked questions

What is the BQ24308DSGT battery protection IC used for?

It is a single-chip Li-Ion battery protection IC that monitors the battery voltage and current, and disconnects the load when an over-voltage, under-voltage, over-current, or over-temperature fault is detected. Typical applications include portable electronics, power tools, and automotive battery modules where a hard-wired safety disconnect is required.

Can BQ24308DSGT replace BQ24308DSGR?

Both share the same base product number BQ24308 and identical protection functions. The difference is the packaging option: DSGT is Tape & Reel, while DSGR is typically Cut Tape. Electrically they are the same die, so one can replace the other as long as the reel format matches your assembly line's feeder requirements.

Is BQ24308DSGT RoHS compliant and lead-free?

Yes, the BQ24308DSGT is listed as RoHS compliant and lead-free, suitable for use in products subject to RoHS directives.
