IRAUTOHBR1

Overview

The IRAUTOHBR1 is an automotive-grade half-bridge motor driver IC manufactured by Infineon Technologies. It integrates high-side and low-side power MOSFETs to drive inductive loads such as DC motors, solenoids, and lamps. The device supports a load voltage up to 35V and delivers a continuous output current of 6A. Designed for robust performance in harsh automotive environments, it features integrated protection mechanisms including over-current, over-temperature, and short-circuit protection. The component operates within the specified automotive temperature range and complies with AEC-Q100 standards.

Feature Summary

• Integrated half-bridge architecture with dual MOSFETs for efficient motor control
• Automotive qualification ensuring reliability under extreme environmental conditions
• Comprehensive protection suite against thermal overload and electrical faults

Applications

• Automotive window lift systems
• Seat adjustment actuators
• Sunroof and convertible top drives
• Electric wiper motors

Procurement Notes

Verify the specific ordering code suffix to confirm package type and tape/reel specifications. Ensure the component meets the required AEC-Q100 grade for your target application. Cross-reference the datasheet revision date to confirm compatibility with your design requirements. Confirm that the supplier provides original manufacturer packaging to guarantee authenticity.

Selection Notes

Select this component when a compact solution for driving medium-power DC motors is required. The 6A current rating suits applications like power windows and seats. Consider the operating voltage range and thermal dissipation capabilities relative to your system design. Verify interface compatibility with your microcontroller or driver logic levels before integration.

Part Context

Infineon's IRAUTO series focuses on reliable power switching for body electronics. This half-bridge driver complements full-bridge and single-switch variants. It addresses the need for durable, space-saving components in modern vehicle architectures where multiple actuators require independent control.

Replacement Considerations

Check for direct pin-compatible substitutes from Infineon's extended portfolio. Verify if alternative drivers offer higher current ratings or additional diagnostic features. Ensure any replacement maintains the same voltage tolerance and protection logic.
