3 A charge ceiling for single-cell Li-Ion
The BQ25616JRTWT is a single-cell Lithium Ion/Polymer charger IC from Texas Instruments with a programmable charge current up to 3 A maximum. That 3 A ceiling means it can fill a typical 2000–3000 mAh cell in about an hour at the constant-current stage, assuming the input supply and thermal budget hold. The USB interface lets it pull power directly from a USB port or a dedicated adapter up to 13.5 V — useful for designs that need to accept both 5 V USB and higher-voltage travel chargers.
Industrial temp grade and package footprint
Texas Instruments is the sole source; no second-source pin-compatible drop-in exists in the BQ25616 family. The base product number BQ25616 covers several current and package variants — confirm the full suffix JRTWT for the 24-WQFN tape-and-reel option. ROHS3 compliant.
