Product details

Automotive-grade single-cell Li-Ion charger with USB input

Protection and programmability for robust designs

Integrated fault protection covers over-temperature, over-voltage, reverse-current, and short-circuit conditions — non-negotiable for a charger that must survive load dumps and battery disconnect events in a vehicle. Charge current and safety timer are programmable via external resistors, allowing the designer to match the charge profile to the cell capacity without firmware intervention. Maximum supply voltage is 6.4 V.

The Q1 suffix denotes AEC-Q100 automotive qualification.

Frequently asked questions

What is the difference between BQ24075QRGTRQ1 and BQ24075RGTR?

The BQ24075RGTR is the commercial-grade version without the Q1 suffix, typically rated for a narrower temperature range. Both share the same package and pinout.

Is BQ24075QRGTRQ1 compatible with BQ24075?

Yes. The BQ24075QRGTRQ1 is a specific orderable variant of the BQ24075 base design. The Q1 suffix indicates automotive qualification; the base part number BQ24075 covers the same silicon.

What is the exact replacement for BQ24075QRGTRQ1?

There is no exact replacement because the part is active and in production. The BQ24075QRGTRQ1 is the automotive-grade version; if a replacement were needed, TI would issue a PCN with a recommended substitute. For non-automotive designs, the BQ24075RGTR is a functional equivalent.
