Product details

Charger IC for single-cell Li-Ion/Polymer packs

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.

Frequently asked questions

What is the maximum charge current for BQ25606RGER?

The maximum charge current is 3A, programmable via an external resistor. The actual current is set below 3A to stay within the thermal limits of the 24-VQFN package.

Is BQ25606RGER compatible with single cell Li-Po batteries?

Yes, it is designed for single-cell Li-Ion and Li-Polymer batteries with a pack voltage up to 4.4V.
