Technical 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.
