Product details

24V input ceiling and 2-3 cell charge count

The BQ24715RGRT: Maximum supply voltage is 24 V, which sets the input rail limit for the charger front end. The part supports 2 to 3 series Li-ion cells.

SMBus interface — host-controlled charging

Communication runs over SMBus, meaning charge current, voltage thresholds, and termination are set by the system host, not by resistor dividers. That buys flexibility in firmware but adds a dependency on the EC or embedded controller having an SMBus port. If you need a standalone charger with pin-strap configuration, this is not the part.

20-VQFN package — thermal pad layout

Housed in a 20-VQFN (3.5x3.5 mm) with an exposed thermal pad. The datasheet layout recommendation is worth following — skipping the thermal vias will cost you derating.

Frequently asked questions

What is the closest pin-compatible alternative to BQ24715RGRT?

Within the same Texas Instruments charger family, the BQ24725 is a common cross-shop candidate but it supports 2-4 cells versus the BQ24715's 2-3 cells. Pin compatibility should be verified against both datasheets before committing a board spin.

Can BQ24715RGRT charge lithium polymer batteries?

Yes — the battery chemistry is listed as Lithium Ion, which covers standard Li-Po cells. The charge algorithm is the same CC/CV profile. Confirm the termination voltage matches your cell specification.
