Overview
The DRV8880RHRT is a dual half-bridge stepper motor driver and dual H-bridge DC motor driver from Texas Instruments. It operates on a supply voltage range of 6.5 V to 45 V with a continuous output current of 2 A per bridge. The device integrates a self-tuning algorithm for automatic optimization of motor performance. It supports step resolutions of 1, 1/2, 1/4, 1/8, and 1/16. The component is housed in a WQFN-28 package and functions within a junction temperature range of -40°C to 150°C.
Feature Summary
- Integrates an automatic self-tuning algorithm to optimize motor operation without manual configuration.
- Provides full integration of control logic and power stages for simplified design.
- Supports multiple microstepping resolutions including 1/16 for smooth motion control.
Applications
- Bipolar stepper motor control systems
- Dual H-bridge brushed DC motor drives
- General purpose motion control applications
Procurement Notes
Verify the specific suffix RHRT against the official datasheet to confirm the reel quantity and tape specifications. Ensure the ordering part number matches the required packaging format. Confirm that the component status is active and not subject to discontinuance notices before finalizing procurement plans.
Selection Notes
Select this component when a dual half-bridge solution is required for bipolar stepper motors or dual DC motors. The integrated self-tuning feature reduces design complexity compared to drivers requiring manual parameter adjustment. Verify that the 2 A current rating and 45 V maximum voltage align with the target motor specifications.
