Product details

Programmable charge current and protection set

Charge current is set via an external resistor — constant-current programmable, so the BOM can be tuned for the specific cell capacity and charge time target. The 1A maximum covers the majority of small-format Li-Ion cells used in wearables, Bluetooth headsets, and medical patches. Over-temperature and over-voltage protection prevent runaway if the input supply or ambient conditions exceed the safe window; short-circuit protection on the output handles a miswired or damaged battery connector.

The part is supplied in a 10-HVSSOP package (3.00 mm width, 0.118" pitch), surface-mount.

Frequently asked questions

Can BQ24090DGQT charge a 1-cell Li-Po battery at 1A?

Yes. The BQ24090DGQT is designed for single-cell Li-Ion/Polymer batteries with a 4.2V termination voltage and supports a programmable charge current up to 1A.

What are the alternatives or equivalent parts to BQ24090DGQT?

Within the same TI family, the BQ24090 series shares the same base functionality and package footprint. For a pin-compatible alternative with the same charge current and protection set, the BQ24090DGQR (same die, different reel quantity) is a direct drop-in. No other manufacturer cross is listed in the official record.
