Overview
The DRV8311HRRWRQ1 is an automotive-grade three-phase PWM motor driver designed for brushless DC (BLDC) motors. It integrates three half-bridge MOSFETs with a typical on-state resistance of 210 mΩ and supports a peak current drive of 5 A. The device operates within a supply voltage range of 3 V to 20 V, with an absolute maximum rating of 24 V. It features integrated current sensing amplifiers without external resistors and includes built-in protection mechanisms such as overcurrent protection, thermal warning, and shutdown. The component utilizes a WQFN-24 package suitable for surface-mount installation.
Feature Summary
- Integrates three half-bridge MOSFETs optimized for driving three-phase BLDC motors
- Includes integrated current sensing amplifiers eliminating the need for external sense resistors
- Supports multiple control interfaces including hardware PWM and SPI-based generation modes
- Provides comprehensive protection against overcurrent, under-voltage, and overheating conditions
Applications
- Three-phase brushless DC motor control in automotive systems
- Electric power steering actuators
- Water pump and cooling fan controllers

Procurement Notes
Verify the specific suffix 'HRRWR' against the official Texas Instruments datasheet to confirm pinout compatibility and functional equivalence. Ensure the component meets AEC-Q100 automotive reliability standards required for your application environment. Confirm that the logic input voltage levels align with your microcontroller's output specifications before integration.
Selection Notes
Select this variant when integrating three-phase BLDC motors requiring high current capability and integrated current sensing. The HRRWR suffix indicates a specific package and temperature grade; verify it matches your PCB footprint and operating temperature requirements. Consider the tSPI interface if minimizing MCU I/O pins is critical for complex multi-motor systems.
Part Context
This component belongs to the DRV8311-Q1 family of automotive motor drivers. It is designed to replace discrete MOSFET solutions by integrating gate drivers, charge pumps, and protection circuits into a single compact package. The series supports various control modes to accommodate different system architectures and complexity levels.
Replacement Considerations
Direct substitutes include other variants within the DRV8311-Q1 family such as DRV8311SRRWRQ1 or DRV8311PQRRWRQ1, provided the package and interface requirements match. Verify electrical characteristics and pin compatibility before substitution.
