Overview
The DRV8245SQRXZRQ1 is an automotive-grade H-bridge driver from Texas Instruments, designed for high-current applications. It features a 32 A output current capability and supports a supply voltage range of 4.5 V to 35 V. The device operates within a temperature range of -40°C to +125°C and utilizes a 28-VQFN-HR package. It integrates current sense and diagnostics, supporting PWM and SPI interfaces for precise motor control in automotive environments.
Feature Summary
- Fully integrated H-bridge driver with built-in current sensing and diagnostic capabilities
- Automotive grade qualification compliant with AEC-Q100 standards
- Supports bipolar stepper and brushed DC motor types via PWM and SPI interfaces
Applications
- Automotive seat positioning systems
- Active grille shutters
- Throttle body actuators
- Fuel pump motors
Procurement Notes
Verify the specific suffix RXZR indicates the 28-VQFN-HR package variant when sourcing. Confirm AEC-Q100 Grade 1 compliance requirements match your system design. Ensure ESD handling procedures are followed due to moisture sensitivity level 3 classification. Cross-reference pinouts with official datasheets to avoid integration errors during PCB layout.
Selection Notes
Select this component for applications requiring high continuous current up to 32 A in compact automotive spaces. The integrated diagnostics simplify fault detection compared to discrete solutions. Consider thermal management requirements given the power dissipation at high currents. Verify that the SPI interface compatibility aligns with the host microcontroller's communication protocols.
Part Context
This part belongs to the DRV824x-Q1 family of automotive H-bridge drivers. It shares functional similarities with other variants like DRV8245SQPWPRQ1 but differs in packaging and potentially thermal characteristics. The family is designed to replace older discrete driver solutions with a single highly integrated IC.
Replacement Considerations
Direct substitutes include DRV8245HQPWPRQ1 and DRV8245HQRXZRQ1. Verify package dimensions and pinout compatibility before substitution. Check if the alternative variant meets the same AEC-Q100 grade and current rating specifications.
