MC33HB2000EKR2

Overview

The MC33HB2000EKR2 is a monolithic H-bridge power integrated circuit designed for brushed DC motor applications. It integrates four low Rds(on) MOSFETs, gate drivers, charge pump, and protection logic in a single package. The device supports input voltages from 5V to 28V with peak tolerance up to 40V. Key programmable features include selectable current limits of 5.4A, 7.0A, 8.8A, or 10.7A via SPI interface. Slew rate control offers eight adjustable settings ranging from 0.25 V/μs to over 16 V/μs. Comprehensive diagnostics monitor charge pump under-voltage, output shorts, load open circuits, and thermal conditions.

Feature Summary

• Integrated H-bridge architecture with built-in MOSFETs and protection circuits
• SPI-configurable current limiting and slew rate adjustment
• Real-time diagnostic reporting for fault detection and system health monitoring
• Wide operating voltage range suitable for various battery-powered systems

Applications

• Robotics joint actuation
• Electric vehicle components such as e-scooters
• Industrial valve execution mechanisms
• Automotive brushed DC motor control

Procurement Notes

Verify the specific suffix 'EKR2' corresponds to the reel packaging format when ordering. Confirm that the target application voltage remains within the 5V to 28V operational range. Ensure the microcontroller interface supports SPI communication for configuring current limits and reading diagnostic status registers. Check for compatibility with the required thermal management solutions given the integrated power stage design.

Selection Notes

Select this component when a compact, high-integration solution for brushed DC motors is required. It is suitable for designs needing precise current control and detailed fault feedback without external discrete MOSFETs. Consider the SPI configurability for optimizing performance across different motor types. Evaluate the thermal dissipation requirements based on the selected current limit and ambient conditions.
