DRV8702QRHBRQ1

Overview

The DRV8702QRHBRQ1 is an automotive-grade half-bridge gate driver manufactured by Texas Instruments. It operates within a supply voltage range of 5.5 V to 45 V and supports PWM input interfaces for precise motor control. The device integrates smart gate drive capabilities to optimize switching performance and reduce electromagnetic interference. Designed for robust operation, it functions reliably across an extended temperature range from -40°C to +125°C. The component is housed in a 32-pin VQFN package with exposed thermal pad, facilitating efficient heat dissipation for high-current applications.

Feature Summary

• Integrates smart gate drive technology for optimized MOSFET switching and reduced EMI
• Supports PWM input signals for direct microcontroller interfacing without additional logic
• Provides comprehensive protection features including overcurrent, overtemperature, and undervoltage lockout

Applications

• Automotive brushed DC motor control systems
• Active grille shutters and cooling fan drivers
• Power window and seat adjustment actuators
• Electronic throttle body control modules

Procurement Notes

Verify the specific suffix (RHBR) confirms the tape-and-reel packaging format required for automated assembly processes. Confirm AEC-Q100 qualification status aligns with target automotive reliability standards. Ensure the operating voltage range matches the system's power rail specifications to prevent undervoltage lockout or overvoltage damage during transient conditions.

Selection Notes

Select this component when designing single-motor drives requiring integrated half-bridge control rather than discrete solutions. Consider the 32-VQFN package for space-constrained PCB layouts where thermal management via the exposed pad is feasible. Evaluate the PWM input compatibility with the host controller's logic levels to ensure signal integrity without external level shifting circuitry.

Part Context

This part belongs to the DRV870x-Q1 family of automotive half-bridge gate drivers. It shares functional similarities with the DRV8703-Q1 but differs in specific pin configurations and current handling characteristics. The series is designed to replace legacy discrete MOSFET drivers, offering higher integration and improved efficiency for modern automotive electrification architectures.
