DRV8804PWP

Overview

The DRV8804PWP is a unipolar stepper motor driver manufactured by Texas Instruments, housed in a 20-pin SOIC package. It integrates power MOSFETs to drive one coil of a stepper motor or other actuators. The device supports an operating supply voltage range from 8.2 V to 60 V and delivers a continuous output current of 1.5 A. It features low on-resistance switches for efficient operation. Internal protection mechanisms include overcurrent protection, short-circuit protection, undervoltage lockout, and overtemperature shutdown. The component operates within a temperature range of -40°C to +125°C.

Feature Summary

• Integrates four low-side N-channel power MOSFETs configured for unipolar stepper motor driving
• Provides comprehensive internal protection against overcurrent, short circuits, undervoltage, and overheating
• Supports wide input voltage ranges up to 60 V with integrated control and power stages

Applications

• Unipolar stepper motor control in office automation machines
• Actuator driving in industrial automation systems
• Motor control applications in gaming machines

Procurement Notes

Verify the specific suffix PWP corresponds to the tube packaging variant, as the tape-and-reel version uses the PWPR suffix. Confirm that the component status is End-of-Life (EOL) prior to procurement planning. Check manufacturer notices for discontinuance dates and recommended replacement parts. Ensure compatibility with existing PCB footprints for the 20-SOIC package. Validate supply chain sources for genuine Texas Instruments products.

Selection Notes

Select this component when driving unipolar stepper motors requiring up to 1.5 A at voltages up to 60 V. Consider the 20-SOIC package size for board space constraints. Evaluate thermal management requirements due to power dissipation at higher currents. Compare against bipolar drivers if the application requires different winding configurations. Verify interface compatibility with the host microcontroller logic levels.

Part Context

The DRV8804 belongs to the DRV88xx family of Europa Motor Drivers designed for printers, scanners, and office automation. It complements other variants like the DRV8803 and DRV8801, which offer different current ratings and bridge configurations. This series emphasizes integration of control logic with power stages to simplify system design for automated equipment manufacturers.
