Overview
The DRV3203QPHPRQ1 is a three-phase brushless motor driver designed for automotive applications. It features an NMOS pre-driver output configuration and operates within a supply voltage range of 5.3V to 28.5V. The device is housed in a 48-pin HTQFP package, suitable for surface mount technology. It supports SPI interface communication for control and diagnostics. The component is rated for operation between -40°C and +125°C, ensuring reliability in harsh environments.
Feature Summary
- Three-phase brushless DC motor driver with integrated NMOS pre-driver outputs
- Supports serial peripheral interface (SPI) for configuration and monitoring
- Automotive-grade qualification for high-temperature and vibration resistance
Applications
- Automotive cooling fans
- Electric power steering systems
- Thermal management pumps
Procurement Notes
Verify the specific suffix PHPRQ1 matches the required tape-and-reel packaging quantity and moisture sensitivity level. Confirm the automotive grade AEC-Q100 status aligns with your system's reliability requirements. Ensure the HTQFP-48 footprint matches your PCB layout constraints before finalizing procurement.
Selection Notes
Select this component when driving three-phase BLDC motors in automotive thermal or steering applications. It is appropriate for systems requiring SPI-based digital control rather than analog PWM inputs. Consider the 28.5V maximum supply limit and ensure the load current remains within the pre-driver capabilities without external gate drive amplification.
Part Context
This part belongs to Texas Instruments' automotive motor driver portfolio, specifically targeting brushless DC motor control. It complements other TI solutions by providing a dedicated pre-driver stage for three-phase topologies. The Q1 designation indicates compliance with automotive quality standards, distinguishing it from general-purpose industrial variants.
Replacement Considerations
Direct substitutes include other TI automotive BLDC drivers such as the DRV3205Q or DRV3206Q, depending on the required current handling and feature set. Verify pin compatibility and software register maps when migrating from legacy parts like the DRV3203EVM reference design components.
