Product details

It delivers a peak 2.5 A source and 5 A sink current, with a typical rise time of 15 ns and fall time of 7 ns, which gives you clean, fast switching at the Miller plateau without excessive ringing if the layout is tight. The non-inverting input and logic thresholds of 1.2 V (VIL) and 2.2 V (VIH) mean it interfaces directly with 3.3 V or 5 V PWM outputs from a controller or MCU. The supply range from 10 V to 32 V covers standard bias rails used in motor drives, battery chargers, and industrial power supplies.

The 140°C TJ max gives headroom in a motor-drive cabinet or an engine bay, but the thermal design still needs to keep the junction below that ceiling under continuous high-frequency switching.

Frequently asked questions

Is UCC27531D compatible with 5V logic?

Yes. The logic thresholds are 1.2 V (VIL) and 2.2 V (VIH), so a 3.3 V or 5 V PWM signal from a microcontroller or DSP will drive it directly without a level shifter.

What is the closest pin-compatible alternative to UCC27531D in this component family?

Within the same UCC27531 family, the UCC27531D is the standard version. Other variants may differ in package or temperature grade, but the base pinout is shared across the series. For a specific alternate, check the TI cross-reference guide or the base product number UCC27531.
