DRV10982QPWPRQ1

Overview

The DRV10982-Q1 is an automotive-grade, three-phase sensorless brushless DC (BLDC) motor driver featuring integrated power MOSFETs. It provides a continuous drive current of up to 2 A and supports peak currents up to 3 A. The device operates within a supply voltage range of 4.5 V to 28 V and functions across an extended temperature range from -40°C to +125°C. Packaged in a 24-pin PowerTSSOP with a width of 4.40 mm, it integrates protection features including overcurrent, overvoltage, undervoltage lockout, and thermal shutdown.

Feature Summary

• Integrated three-phase bridge with internal power MOSFETs for compact design
• Sensorless control algorithm optimized for BLDC motors without position sensors
• Comprehensive protection mechanisms including thermal and electrical fault handling

Applications

• Automotive cooling fans and blowers
• Electric power steering systems
• Thermal management pumps in electric vehicles

Procurement Notes

Verify the specific suffix PWPR indicates the 24-PowerTSSOP package configuration. Confirm the Q1 designation aligns with automotive reliability standards required for your application. Ensure compatibility with your system's voltage rails and thermal dissipation requirements before ordering.

Selection Notes

Select this component when a robust, integrated solution for sensorless BLDC control is needed in automotive environments. It is suitable for applications requiring moderate current levels around 2 A continuous. Consider alternative models if higher peak currents or different package footprints are necessary.

Part Context

This part belongs to Texas Instruments' DRV1098x family of automotive BLDC drivers. It shares architectural similarities with the DRV10983 but differs in specific current ratings and feature sets. The Q1 suffix denotes qualification for automotive use, ensuring compliance with AEC-Q100 standards for durability and performance under harsh conditions.

Replacement Considerations

Check for DRV10983QPWPRQ1 as a potential variant within the same family. Verify pin-to-pin compatibility and current capabilities against existing designs before substitution.
