Overview
The DRV8804DWR is a quad serial interface low-side driver IC manufactured by Texas Instruments. It integrates four N-channel MOSFETs with overcurrent protection and inductive clamp diodes. The device operates within an input voltage range of 8.2 V to 60 V and supports output currents up to 1.5 A per channel. It features a sleep mode with a typical quiescent current of 1.6 mA. The component is housed in a 20-pin SOIC (DW) package and functions across a temperature range of -40°C to +125°C.
Feature Summary
- Integrates four protected low-side drivers with integrated inductive clamp diodes
- Features a serial interface for control configuration
- Includes overcurrent protection for each output channel
Applications
- Unipolar stepper motor driving
- Brushed DC motor control
- Solenoid and relay actuation
Procurement Notes
Verify the specific suffix against official documentation, as variations may exist between tube and reel packaging formats. Confirm that the requested revision matches the current production status. Ensure compatibility with existing board layouts regarding the SOIC-20 footprint. Check for any recent product change notices affecting pinout or electrical characteristics before finalizing procurement orders.
Selection Notes
Select this component when a compact solution for multiple low-side loads is required. It is suitable for applications needing independent control of four channels via a serial interface. Consider the thermal performance of the SOIC-20 package for high-current scenarios. Evaluate the need for integrated clamping diodes to simplify external circuit design compared to discrete solutions.
Part Context
This part belongs to the DRV880x family of motor drivers from Texas Instruments. It serves as a low-side switching solution distinct from full-bridge variants like the DRV8803 or DRV8805. The series is designed for cost-effective control of inductive loads in automotive and industrial environments.
Replacement Considerations
The DRV8804DW is the tube-packaged equivalent of this reel-based component. Verify if the functional specifications remain identical before substitution.
