Charger IC for single-cell Li-Ion/Polymer packs
The Texas Instruments BQ25606RGER is a single-cell Li-Ion/Polymer battery charger IC with a USB interface, designed to charge one cell up to 4.4V pack voltage at a programmable constant current up to 3A max. It integrates over-temperature, over-voltage, and short-circuit fault protection, making it suitable for portable devices where battery safety is critical.
3A charge current and thermal management
The 3A max charge current is programmable, so you set the rate to match the battery capacity and thermal budget. The USB interface handles input from a standard USB port or a dedicated adapter; the charger negotiates the input current limit automatically.
24-VQFN rework considerations
The 24-VFQFN Exposed Pad (4x4 mm) package is surface-mount with a centre thermal pad.
