MC33HB2000AESR2

Overview

The MC33HB2000AESR2 is a monolithic H-bridge power IC designed for brushed DC motor control in automotive and industrial applications. It integrates four low Rds(on) MOSFETs, gate drivers, charge pump, and protection circuits within a compact HVQFN package. The device supports input voltages from 5V to 28V with peak tolerance up to 40V. Key features include SPI programmability for current limiting (5.4A, 7.0A, 8.8A, 10.7A) and slew rate adjustment across eight levels. Comprehensive diagnostics via SPI monitor charge pump status, output shorts, load open conditions, and thermal warnings.

Feature Summary

• Integrated H-Bridge Driver: Combines power MOSFETs, gate drivers, and logic control in a single chip to simplify PCB layout and reduce component count.
• SPI Programmability: Allows dynamic configuration of current limit thresholds and output slew rates for optimized motor performance and protection.
• Advanced Diagnostics: Provides real-time monitoring of system health including over-temperature, under-voltage, short-circuit, and open-load conditions via serial interface.
• Robust Protection: Includes reverse battery protection, thermal shutdown, and over-current protection to ensure reliability in harsh environments.

Applications

• Automotive Engine Control Units (ECU)
• Electric Vehicle (EV) systems
• Industrial valve actuators
• Robotics joint drives

Procurement Notes

Verify the specific suffix 'AESR2' against official NXP documentation to confirm tape-and-reel packaging and temperature grade. Ensure compatibility with your target voltage range and thermal management requirements. Cross-reference pinouts with the latest datasheet revision to avoid integration errors during schematic capture.

Selection Notes

Select this component when high integration and diagnostic capabilities are required for brushed DC motor control. It is suitable for applications needing precise current limiting and remote status monitoring via SPI. Consider thermal dissipation needs based on the HVQFN package and expected duty cycles. Compare with HB2001 if enhanced SMARTMOS features are not critical.

Part Context

Part of the HB2000 family, which includes variants like HB2000AES and HB2000ES. These devices address space, heat, and cost constraints in modern automotive electrification by replacing discrete MOSFET solutions. The family targets increasing motor counts in ECUs and EVs, offering improved thermal performance through advanced packaging technologies.

Replacement Considerations

Check for HB2000AES or HB2000ES equivalents depending on packaging and temperature specifications. Verify functional compatibility with existing firmware due to potential differences in register maps or diagnostic codes between revisions.
