Product details

3 A charge current for 1-cell Li-ion packs

The BQ25616RTWR from Texas Instruments is a single-cell Li-Ion/Li-Polymer linear charger IC that delivers a programmable constant charge current up to 3 A via a USB input. It handles a battery pack voltage up to 4.35 V and accepts a supply input up to 13.5 V, making it suitable for USB-C PD or standard 5 V adapters.

Industrial temperature and fault protection

On-chip fault protection covers over-current and over-voltage events, reducing external supervisor circuitry.

24-WQFN exposed-pad package — thermal design note

The supplier device package is 24-WQFN (4x4).
