Overview
The DRV3220QPHPRQ1 is an automotive-grade three-phase brushless DC motor gate driver manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 60 V and supports junction temperatures from -40°C to +125°C. The device delivers 1 A output current per channel and features a 48-HTQFP package with dimensions of 7x7 mm. It is qualified under AEC-Q100 standards for reliability in harsh automotive environments.
Feature Summary
- Provides three half-bridge outputs for driving three-phase BLDC motors
- Supports PWM interface for precise motor control and commutation
- Integrated functional safety capabilities aligned with automotive requirements
- Robust protection mechanisms against reverse polarity and over-current conditions
Applications
- Automotive electric power steering systems
- Electric cooling fan controllers
- Blower motor drivers in HVAC units
- Pump control modules in vehicle thermal management
Procurement Notes
Verify component authenticity through authorized channels due to limited availability. Confirm package marking matches the 48-HTQFP specification. Check datasheet revisions for any updates to electrical characteristics or pinout configurations before integration into production designs.
Selection Notes
Select this component when designing three-phase BLDC motor drives requiring high voltage tolerance up to 60 V. Ensure the application demands a 1 A drive current capability. Consider the HTQFP-48 footprint constraints and SPI/PWM interface compatibility with the host microcontroller for optimal system integration.
Part Context
This part belongs to the DRV3220-Q1 series, designed specifically for automotive motor applications. It complements other TI gate drivers like the DRV3245 by offering dedicated three-phase control without integrated FETs, allowing designers to select external MOSFETs based on specific current and thermal requirements.
Replacement Considerations
The DRV3245SQPHPRQ1 serves as a related alternative within the same family, though it may offer different integration levels or performance specifications. Verify pin-to-pin compatibility and electrical parameter alignment before substitution.
