Product details

Package and thermal considerations

The 24-WQFN (4x4 mm) with exposed pad requires a thermal land on the PCB to dissipate heat during high-current charging. The pad must be soldered to a copper plane; a via array under the pad improves thermal transfer. The part is specified for surface-mount assembly only — no through-hole option.

Lifecycle and compliance

The BQ25616RTWT carries an active lifecycle status and is ROHS3 compliant. For new designs, this part is a current-production choice with standard lead times through distribution.

Frequently asked questions

What is the maximum charge current and battery voltage for BQ25616RTWT?

The maximum charge current is 3A, and the battery regulation voltage is 4.35V. Confirm your cell's maximum voltage rating before use.

Is BQ25616RTWT compatible with USB Type-C?

The part lists USB as its interface, but the evidence does not specify USB Type-C compliance. Verify with the datasheet whether the charger negotiates Type-C current levels or requires an external PD controller.
