Overview
The DRV8703DQRHBTQ1 is an automotive-grade brushed DC motor driver featuring a half-bridge topology. It operates within a supply voltage range of 5.5 V to 45 V and delivers an output current of 30 mA. The device functions at a working frequency of 100 kHz with a quiescent supply current of 7.5 mA. It supports PWM interface control and includes two outputs. The component is housed in a 32-VQFN package (5x5 mm) and meets AEC-Q100 qualification standards for automotive applications.
Feature Summary
- Integrated smart gate drive technology designed for automotive reliability
- Fully integrated control and power stage for simplified design
- Supports independent half-bridge or PWM operation modes
Applications
- Automotive brushed DC motor control systems
- Motion control applications requiring half-bridge driving
- Ignition controller driver circuits
Procurement Notes
Verify the specific suffix 'D' indicates the qualified automotive grade variant when sourcing. Confirm the package type matches the 32-VQFN footprint requirements. Ensure the order quantity aligns with the manufacturer's standard reel specifications. Cross-reference the datasheet revision to confirm compatibility with existing design parameters.
Selection Notes
Select this component for applications requiring a compact, automotive-qualified half-bridge solution. It is suitable for low-current brushed DC motor drives where space efficiency is critical. Consider the 30 mA output limit when sizing the load. The integrated nature reduces external component count compared to discrete solutions.
Part Context
This part belongs to the DRV870xD-Q1 family of automotive half-bridge gate drivers. It shares functional similarities with the DRV8702D-Q1 but offers specific configuration options. The series is designed to meet stringent automotive reliability standards while providing robust motor control capabilities in a small form factor.
Replacement Considerations
The DRV8703QRHBRQ1 is a non-qualified alternative within the same family. Verify if the automotive qualification is strictly required for the target application before substituting.
