DRV8803PWPR

Overview

The DRV8803PWPR is a fully integrated stepper motor driver and controller manufactured by Texas Instruments. It features four low-side outputs capable of delivering up to 2 A per channel, supporting unipolar stepper motors with current settings adjustable from 150 mA to 2 A. The device operates within a supply voltage range of 8.2 V to 60 V and includes an internal charge pump for gate drive. It utilizes a 16-pin HTSSOP package and supports PWM frequencies up to 40 kHz. The component is designed for high efficiency and thermal performance in motion control applications.

Feature Summary

• Fully integrated control and power stage for unipolar stepper motors
• Adjustable output current ranging from 150 mA to 2 A per channel
• Internal charge pump enables operation at low supply voltages
• Supports microstepping resolutions including full, half, quarter, eighth, sixteenth, and thirty-second step modes

Applications

• Unipolar stepper motor control systems
• Solenoid and relay drivers
• General-purpose low-side switching applications
• Motion control modules requiring precise step resolution

Procurement Notes

Verify the suffix 'PWP' indicates the tube package while 'PWPR' denotes the reel package configuration. Confirm that the specific order quantity aligns with the manufacturer's standard packaging requirements for the selected variant. Ensure compatibility with the intended PCB footprint for the 16-HTSSOP package before finalizing procurement decisions.

Selection Notes

Select this component when a fully integrated solution for unipolar stepper motors is required without external logic gates. Consider the 2 A peak current capability and the wide operating voltage range up to 60 V. Evaluate the need for specific microstepping resolutions supported by the internal logic. Ensure the thermal management strategy accounts for the power dissipation characteristics of the HTSSOP-16 package under maximum load conditions.

Part Context

This part belongs to the DRV8803 family of motor drivers from Texas Instruments. It serves as a complete motion control solution, combining logic control with power MOSFET outputs. The family is designed to simplify system design by integrating necessary protection features and control interfaces into a single compact package suitable for various industrial automation tasks.

Replacement Considerations

The DRV8803PWP is a direct functional equivalent offered in a tube package instead of a reel. Both variants share identical electrical specifications and pinouts. Designers should verify that the manufacturing process change from tube to reel does not impact existing assembly line handling procedures or reflow profiles.
