TIDRV8870EVM
Overview
The DRV8870EVM is a complete evaluation module designed to demonstrate the capabilities of the DRV8870 brushed DC motor driver. It supports a wide operating voltage range from 8V to 40V and allows for immediate evaluation of the integrated H-bridge driver. The board features a built-in potentiometer for easy manual speed control and local PWM generation.
Why Choose This Part
The board provides a simplified interface for testing the DRV8870's integrated current regulation and protection features. It eliminates the need for an external microcontroller for basic testing thanks to the onboard potentiometer and PWM logic.
Applications
Key Specifications
Getting Started
Connect a power supply between 8V and 40V to the terminal blocks and attach a brushed DC motor to the output headers. Use the onboard potentiometer to adjust the motor speed or bypass it to provide your own external PWM signal for microcontroller-based testing. Refer to the TI user guide for specific jumper settings regarding current limit thresholds.
