Overview
The DRV8245HQPWPRQ1 is an automotive-grade, fully integrated H-bridge motor driver manufactured by Texas Instruments. It features a dual half-bridge output configuration capable of delivering up to 32 A continuous current per channel. The device supports both PWM and SPI interfaces for control and diagnostics. It operates with a supply voltage range of 4.5 V to 35 V and is designed for bipolar and unipolar stepper motors as well as brushed DC motors. The component is housed in a 28-pin PowerTSSOP package and complies with AEC-Q100 standards for automotive applications.
Feature Summary
- Fully integrated power stage with built-in protection mechanisms
- Supports bidirectional control via PWM or serial interface
- Automotive qualification ensuring reliability under harsh conditions
Applications
- Automotive seat actuation systems
- Power window and sunroof drives
- Thermal management fan control in vehicles
Procurement Notes
Verify the specific suffix 'HQ' against the official datasheet to confirm pinout and thermal characteristics match your design requirements. Ensure the PCB layout accommodates the 28-PowerTSSOP footprint and adequate copper area for heat dissipation given the high current capability. Confirm that the SPI interface signals are compatible with your microcontroller logic levels before finalizing the bill of materials.
Selection Notes
Select this component when high current drive is required for automotive motor applications. It is suitable for designs needing integrated protection and diagnostic feedback through SPI. Consider the thermal performance of the PowerTSSOP package relative to your system's ambient temperature constraints. Verify that the 35 V maximum supply voltage aligns with your vehicle's electrical architecture.
Part Context
This part belongs to the DRV8245 family of automotive motor drivers from Texas Instruments. It shares the core architecture with variants like the DRV8245SQPWPRQ1 but may differ in specific packaging or qualification details. The family is designed to simplify motor control implementation by integrating gate drivers, power MOSFETs, and protection circuits into a single compact solution.
Replacement Considerations
The DRV8245SQPWPRQ1 is a related variant within the same product family. Verify if the specific suffix differences impact pin compatibility or thermal performance for your application.
