MC33932EK

Overview

The MC33932EK is a dual 5.0 A throttle control H-bridge motor driver manufactured by NXP Semiconductors. Designed for automotive applications, it operates within a supply voltage range of 5 V to 28 V and supports an output current of 5 A per channel. The device features a SOIC-Wide-EP-32 package and complies with the AEC-Q100 qualification standard for automotive grade components. It includes integrated current feedback and sleep modes to enhance system efficiency and protection in brushed DC motor control scenarios.

Feature Summary

• Dual high-current H-bridge configuration supporting 5 A continuous output per channel
• Integrated current feedback mechanism for precise motor control and protection
• Automotive-grade reliability compliant with AEC-Q100 qualification standards
• Supports low-power sleep mode operation to minimize standby energy consumption

Applications

• Brushed DC motor drivers in automotive throttle control systems
• Small engine control units requiring robust motor actuation
• Industrial motor control interfaces needing high current capability

Procurement Notes

Verify the specific suffix EK against official NXP documentation to confirm package type and tape/reel specifications. Ensure compatibility with your target PCB footprint, as the SOIC-Wide-EP-32 package requires precise thermal management considerations. Cross-reference the datasheet revision date to guarantee alignment with your design's regulatory and performance requirements before finalizing procurement.

Selection Notes

Select this component when designing systems that require dual-channel high-current motor driving with integrated diagnostic feedback. The AEC-Q100 qualification makes it suitable for harsh automotive environments. Compare its 5 A output capability and SOIC-Wide-EP-32 packaging against alternatives like the MC33931EK if single-channel or different pinout configurations are needed. Ensure the 5 V to 28 V operating range matches your power supply architecture.
