Overview
The DRV3245BQPHPRQ1 is an automotive-grade three-phase brushless DC motor controller manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 45 V and supports battery voltages as low as 2 V. The device delivers an output current of 1 A per phase and functions reliably across an extended temperature range from -40°C to +125°C. It is housed in a 48-pin HTQFP package and holds AEC-Q100 qualification for automotive applications.
Feature Summary
- Integrated three-phase BLDC motor control with built-in gate drivers
- Supports low-voltage operation starting at 2 V battery input
- Automotive reliability certified under AEC-Q100 standards
Applications
- Automotive body electronics systems
- Electric power steering actuators
- Thermal management pumps in vehicles
Procurement Notes
Verify the complete part number including the suffix QPHPRQ1 to ensure correct packaging and automotive grade alignment. Confirm AEC-Q100 certification status matches project requirements. Check moisture sensitivity levels and recommended reflow profiles during assembly planning. Validate compatibility with the BOOSTXL-DRV3245AQ1 development kit if prototyping.
Selection Notes
Select this component for applications requiring robust three-phase motor control in harsh automotive environments. Ensure the system design accommodates the 45 V maximum supply voltage and 1 A output current limits. Consider the HTQFP-48 package constraints for PCB layout and thermal management strategies.
Part Context
This device belongs to the DRV3245Q series of motor controllers designed specifically for automotive use. It integrates control logic and power stages into a single compact solution, reducing component count compared to discrete designs. The series targets high-reliability motion control tasks in modern vehicle architectures.
Replacement Considerations
Consult official substitution lists for equivalent parts within the DRV3245 family or compatible TI motor driver series. Verify pin-to-pin compatibility and electrical parameter alignment before replacing.
