DRV8145HQRXZRQ1

Overview

The DRV8145HQRXZRQ1 is an automotive-grade, fully integrated half-bridge driver from the DRV814x-Q1 family. It supports a supply voltage up to 40 V and delivers a peak current of 46 A. The device features an integrated bootstrap diode and is designed for robust performance in demanding environments with an operating junction temperature range of -40°C to +150°C.

Feature Summary

• Fully integrated half-bridge architecture
• Automotive qualification compliant
• High peak current capability

Applications

• Automotive motor control systems
• General purpose automotive loads
• Ignition circuits

Procurement Notes

Verify the complete part number including the suffix 'RXZRQ1' to ensure correct packaging and automotive grade specification. Confirm that the application environment remains within the specified thermal limits. Cross-reference the datasheet revision date to ensure compatibility with latest design guidelines. Ensure ESD protection measures are implemented during handling.

Selection Notes

Select this component when a single half-bridge solution with high current capacity is required for automotive applications. Compare against other DRV814x variants if lower current or different package options are needed. Verify that the 40 V supply rating matches the system power rail. Consider thermal management requirements due to the high current output capabilities.

Part Context

This device belongs to the DRV814x-Q1 family of automotive half-bridge drivers. It shares functional similarities with other members of the series but offers specific current and packaging characteristics defined by the RXZRQ1 suffix. It is distinct from full-bridge or three-phase motor drivers.

Replacement Considerations

Direct substitutes include other parts within the DRV814x-Q1 family such as DRV8145HQPWPRQ1, provided the package type (HTSSOP vs. VSON) and pinout compatibility are verified. Check datasheets for any differences in thermal resistance or maximum current ratings.
