Product details

Multi-chemistry charger for 2–4 cell packs, 10 A ceiling

The BQ24750ARHDT is a multi-chemistry battery charger controller from Texas Instruments that handles 2 to 4 series cells with a programmable constant-current charge up to 10 A.

10 A charge current and protection features

The 10 A maximum charge current lets this IC charge high-capacity packs quickly, but the external MOSFETs and inductor must be sized for that peak — mind the thermal pad on the 28-VQFN (5x5 mm) exposed pad to keep junction temperature under 125°C. Over-current and over-voltage fault protection are integrated, so you don't need separate comparators; the protection thresholds are set by the charger's internal reference, not external dividers.

For current BOM positions, the active status means you can plan multi-year production without a last-time-buy trigger.

Frequently asked questions

Does BQ24750ARHDT support 4-cell Li-ion batteries?

Yes. The charger handles 2 to 4 series cells. For a 4-cell Li-ion pack, the maximum battery pack voltage is 18.048 V, which matches the typical 4S full-charge voltage of 16.8 V plus margin.

What is the closest alternative to BQ24750ARHDT in the same family?

Within the BQ24750 series, the base product number BQ24750 shares the same charger architecture. The 'ARHDT' suffix indicates the specific package and tape-and-reel option. For a pin-compatible alternative with a different charge-current ceiling, check the BQ24750A variant — confirm the charge current and cell count against your BOM before swapping.
