Product details

Single-cell Li-ion charger for handheld gear

The Texas Instruments BQ25046DQCT is a linear battery charger IC designed for single-cell Li-ion or LiFePO4 packs in handheld and mobile devices. Its 3.3V to 9V input range covers USB (5V) and regulated wall-adapter supplies, and the 1.1A supply current ceiling supports fast charging of 1000–2000 mAh cells without pushing the thermal budget of the 10-WSON package.

1.1A charge current — thermal reality check

At 1.1A charge current, the power dissipation in the linear pass element is (VIN – VBAT) × ICHG. With a 5V input and a 3.7V battery, that is roughly 1.43 W. Layout is not optional; the thermal pad is the primary heat path.

Active production — no allocation signal

For new designs, this means standard franchise-channel availability with no near-term supply risk.

Frequently asked questions

What is the output current of BQ25046DQCT?

The supply current rating is 1.1A. This is the maximum charge current the linear regulator can deliver; actual charge current is set by the external resistor and limited by thermal conditions.

Is BQ25046DQCT compatible with lithium-ion batteries?

Yes, the 3.3V to 9V input range and 1.1A charge current are well-suited for single-cell Li-ion (4.2V termination) and LiFePO4 (3.6V termination) packs used in handheld and mobile devices.
