Product details

Synchronous switch-mode supercapacitor charger – 5V to 28V input

The BQ24640RVAR is a dedicated synchronous switch-mode charger IC for supercapacitor stacks, accepting an input rail from 5V to 28V. This wide input range lets it draw from a regulated 5V bus, a 12V supply, or an unregulated 24V industrial rail without a pre-regulator.

16-VQFN (3.5x3.5) – small footprint with thermal pad

Housed in a 16-VQFN (3.5x3.5) package with an exposed pad, the BQ24640RVAR fits tight PCB layouts common in portable or embedded supercapacitor modules. The IC draws a supply current of 1mA, a low overhead that matters in always-on or low-power standby systems where every milliamp counts.

Active lifecycle – no obsolescence watch needed

The part is ROHS3 Compliant, covering the latest EU restriction requirements — no exemption expiry concern for new designs.

Frequently asked questions

Does BQ24640RVAR work for charging supercapacitors?

Yes, the BQ24640RVAR is specifically designed as a supercapacitor charger. It implements a synchronous switch-mode topology to charge supercapacitor stacks efficiently from the 5V–28V input.
