MC33HB2002ESR2

Overview

The MC33HB2002ESR2 is a dual H-bridge motor driver IC designed for precise control of brushed DC motors in automotive applications. It features an SPI interface for configuration and monitoring, supporting continuous output currents up to 2A per channel. The device operates within a supply voltage range of 5V to 28V and includes current feedback, sleep mode, and thermal protection. Packaged in a 28-pin HVQFN (6x6 mm) with exposed pad, it meets AEC-Q100 automotive qualification standards for reliability under harsh environmental conditions.

Feature Summary

• Dual H-bridge architecture enabling independent control of two brushed DC motors
• SPI interface for programmable settings and real-time status monitoring
• Integrated current feedback and thermal shutdown for robust fault protection
• Automotive-grade qualification ensuring durability in demanding environments

Applications

• Automotive seat adjustment systems
• Window and sunroof actuator control
• Power mirror positioning mechanisms
• Wiper and washer pump drivers

Procurement Notes

Verify the complete part number including the suffix 'ESR2' to ensure correct tape-and-reel packaging and automotive grade specification. Confirm that the design supports the required SPI communication protocol and voltage levels. Check for any specific ordering restrictions or minimum order quantities imposed by authorized distributors. Ensure compatibility with the target PCB footprint for the 28-HVQFN package.

Selection Notes

Select this component when dual brushed DC motor control is required with digital SPI configuration capabilities. It is suitable for applications needing integrated fault protection and high reliability in automotive environments. Consider alternative single-channel drivers if only one motor needs control, or higher-current devices if loads exceed 2A per bridge. Verify that the system voltage falls within the 5V to 28V operating range.

Part Context

This part belongs to NXP's HB2002 family of bipolar motor drivers, specifically optimized for automotive body electronics. The series provides scalable solutions for various motor control needs, from simple actuators to more complex positioning systems. The MC33HB2002 variant offers a balanced combination of performance, integration, and cost-effectiveness for mid-range automotive applications requiring dual motor drive capability.

Replacement Considerations

Direct substitutes may include other dual H-bridge drivers from NXP or competitors with similar SPI interfaces and current ratings. Ensure replacement parts match the 28-HVQFN package dimensions and pinout. Verify that any alternative meets the same AEC-Q100 automotive qualification standards and operates within the same voltage and temperature ranges.
