MC34931EKR2

Overview

The MC34931EKR2 is a monolithic, thermally efficient H-Bridge DC motor driver manufactured by NXP Semiconductors. It supports a supply voltage range of 5 V to 36 V and delivers an output current of 5 A. The device features real-time load current monitoring and automatic thermal shutdown. It operates within a junction temperature range of -40°C to +150°C and has an operating supply current of 20 mA. The component is housed in a 32-lead SOIC-Wide package with exposed pad (SOICW-EP) and is supplied in tape and reel packaging.

Feature Summary

Integrated H-Bridge architecture for fully integrated control and power stage operation
Real-time load current monitoring capability for precise motor management
Automatic thermal shutdown protection to ensure device reliability under stress

Applications

DC Brushed Motor Control
DC Servo Motor Control
Industrial Automation Systems

Procurement Notes

Verify the specific suffix 'R2' indicates tape and reel packaging rather than tube. Confirm the manufacturer is NXP Semiconductors despite the brand listing. Ensure the 36V rating aligns with system requirements. Check RoHS compliance status via official documentation before procurement.

Selection Notes

Select this component for applications requiring high thermal efficiency and robust current monitoring. The 36V rating suits industrial environments. Compare against MC33931EK if 28V limits are acceptable. Verify package compatibility with PCB footprint designs. Consider the 5A continuous current capability for load matching.

Part Context

This part belongs to the MC34931 family of H-Bridge drivers designed for industrial motor control. It serves as a bridge driver IC integrating gate drive and power stages. The EKR2 variant specifically denotes the reel packaging format for automated assembly processes.

Replacement Considerations

MC33931EK is a related variant with a lower 28V maximum voltage rating but similar functionality. Verify voltage headroom requirements when substituting. Packaging differences exist between EK (tube) and EKR2 (reel).
