TIDRV8434EEVM
Overview
The DRV8434EEVM is a complete evaluation platform for the DRV8434E stepper motor driver, designed to showcase advanced current sensing and integrated protection features. The board supports an input voltage range of 4.5V to 48V and can deliver up to 4A peak output current per bridge. It includes an onboard MSP430 microcontroller to handle USB communication and provide a bridge to the Windows-based Graphical User Interface (GUI).
Why Choose This Part
The board features an integrated sense-resistor-less current sensing architecture, reducing PCB footprint and thermal management complexity. It provides high-efficiency power delivery up to 48V and includes a user-friendly GUI for real-time parameter tuning and performance monitoring.
Applications
Key Specifications
Getting Started
Connect a 4.5V to 48V power supply to the VM and GND terminals and interface with a PC via the micro-USB port. Download and install the DRV8434E-EVM GUI software from TI to configure step modes, decay settings, and current limits without writing firmware. Ensure the onboard jumpers are configured correctly for either internal or external step/dir control signals.
