MC34932SEKR2

Overview

The MC34932SEKR2 is a dual H-bridge gate driver manufactured by NXP Semiconductors, designed for driving brushed DC and stepper motors. It operates within a supply voltage range of 5 V to 28 V and delivers an output current of 5 A per channel. The device features four independent drivers with high-side and low-side outputs in an SOIC-EP-54 package. Key electrical characteristics include rise and fall times of 3 µs, maximum on-delay of 18 µs, and maximum off-delay of 12 µs. It supports current feedback and sleep modes, functioning reliably between -40 °C and +85 °C.
