Overview
The DRV3245AEPHPRQ1 is an automotive-grade three-phase BLDC motor gate driver manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 45 V and supports output currents up to 1 A. The device functions reliably across an extended temperature range from -40 °C to +125 °C. It utilizes a 48-pin HTQFP package for surface mount installation. This component belongs to the DRV3245Q series, designed for robust motor control applications in demanding environments.
Feature Summary
- Integrated high-side and low-side gate drivers optimized for three-phase brushless DC motors
- Supports PWM inputs for precise speed and position control
- Includes diagnostic features such as overcurrent protection and thermal shutdown
Applications
- Automotive electronic power steering systems
- Electric vehicle cooling fan controllers
- Blower motor control units
Procurement Notes
Verify the specific suffix 'AE' against official Texas Instruments documentation to confirm exact binning or qualification status. Ensure compatibility with the BOOSTXL-DRV3245AQ1 evaluation module if system testing is required. Confirm humidity sensitivity classification prior to PCB assembly planning.
Selection Notes
Select this component when designing for automotive Grade 1 reliability standards requiring integrated gate driving capabilities. Consider the 48-pin HTQFP footprint for layout constraints. Evaluate the 45 V maximum supply limit against system battery fluctuations. Compare against other DRV3245 variants if different current ratings or pin configurations are needed.
Part Context
This part is part of the DRV3245Q family of motor gate drivers. It shares architectural similarities with other automotive motor control ICs from Texas Instruments. The device integrates necessary logic for commutation while providing robust protection mechanisms essential for safety-critical automotive subsystems.
Replacement Considerations
Consult official substitution lists for equivalent parts within the DRV3245Q series. Verify pin-to-pin compatibility before replacing existing designs.
