DRV8813PWPR

Overview

The DRV8813PWPR is a bipolar stepper motor driver manufactured by Texas Instruments, housed in a 28-pin HTSSOP package. It operates within a supply voltage range of 8.2 V to 45 V and delivers an output current of 1.75 A. The device supports step rates up to 100 kHz and features five selectable microstep resolutions: full, half, quarter, eighth, and sixteenth. Integrated protections include overcurrent protection with automatic current reduction, thermal shutdown, and under-voltage lockout.

Feature Summary

• Integrates a fixed off-time PWM regulator for precise current control
• Provides programmable current limiting with automatic reduction during faults
• Supports multiple microstep resolutions via hardware inputs
• Includes comprehensive on-chip protection mechanisms

Applications

• Bipolar stepper motor control systems
• Industrial automation equipment
• Office automation devices
• Printing machinery

Procurement Notes

Verify the specific suffix 'PWPR' corresponds to the HTSSOP-28 package and tape-and-reel delivery format. Confirm that the component meets RoHS standards and humidity sensitivity level requirements for your assembly process. Ensure the ordering part number matches the exact electrical specifications required for your design implementation.

Selection Notes

Select this component for applications requiring integrated bipolar stepper motor driving with high reliability. It is suitable for designs needing flexible microstepping options and robust fault protection without external discrete components. Consider the thermal performance and package size constraints when integrating into the final system layout.

Part Context

This part belongs to the DRV88xx series of integrated motor drivers from Texas Instruments. These devices are designed to simplify motor drive designs by combining gate drivers, sense amplifiers, and protection circuits. The series targets various motor types including brushed DC, brushless DC, and stepper motors, offering a compact solution for motion control applications.

Replacement Considerations

The DRV8813PWP is the non-reel variant of the same device. Verify pin compatibility and electrical equivalence before substitution. No other direct cross-model replacements are confirmed in the provided documentation.
