DRV8885RHRT

Overview

The DRV8885RHRT is a fully integrated stepper motor driver manufactured by Texas Instruments. It features an NMOS H-bridge architecture with four half-bridge outputs, designed for bipolar stepper motors. The device operates within a load voltage range of 8V to 37V and supports a continuous output current of 1.5A. It utilizes logic-level interfaces and offers step resolutions from full step to 1/16 microstepping. The component is housed in a 28-WQFN package measuring 5.5x3.5mm and functions across a temperature range of -40°C to 125°C.

Feature Summary

• Fully integrated control and power stage for simplified system design
• Supports variable step resolutions including 1/16 microstepping
• Built-in thermal shutdown and over-current protection mechanisms

Applications

• Printer motor control systems
• Office automation equipment
• Industrial motion control applications

Procurement Notes

Verify the specific suffix RHRT corresponds to the tape-and-reel packaging configuration required for your assembly line. Confirm that the 28-WQFN footprint matches your PCB layout guidelines. Ensure the 8V-37V supply range aligns with your system's power delivery capabilities before finalizing procurement.

Selection Notes

Select this component when a compact solution for bipolar stepper motors is needed. It is suitable for applications requiring up to 1.5A per phase. Consider the 28-WQFN package size constraints. Verify compatibility with your host controller's logic voltage levels for reliable interface operation.
