Texas Instruments DRV8818 | Demoboard DRV8818EVM
35-V, 2.5-A bipolar stepper motor driver with current regulation and 1/8 microstepping
Overview
| Topology | Motor Drive |
| Input voltage | 8-35 V |
| IC revision | A |
Description
The DRV8818 evaluation module (EVM) demonstrates the capabilities and performance of the DRV8818 integrated micro-stepping motor driver from Texas Instruments. This EVM comes with an on-board MSP430 microprocessor which has been pre-programmed for standalone operation. The regulated voltage for the MSP430 is provided by TPS77701 single-channel LDO. This EVM operates on power supply voltages from 8 V to 35 V.
Features
Supports stepper motor microstepping up to 1/8 step and up to 2.5A.Advanced graphical user interface (download available below) enables acceleration, deceleration and motion profiles.On-board potentiometers allows for adjusting Vref, decay ratio, blanking time and off time.Control and status signals brought out to test headers for easy evaluation.
Typical applications
- Positioning/Tracking
- Textile Machinery
- Robotics
- Printers
- Factory Automation
