Evaluation Board for Stepper Motor Drive -ROHM-STEPMO_EVK_20F
Manufactured By:ROHM Semiconductor
Part Number ROHM-STEPMO_EVK_20F is no longer available
This evaluation board manual describes the usage of ROHM’s stepper motor driver IC evaluation kit (EVK) called STEPMO_EVK_20x. It is designed as a plug-in board (Shield) for popular Arduino microcontroller platform. This document provides guidelines to quickly setup the hardware and software for fast and easy stepper motor driver IC performance evaluation.
The ROHM-STEPMO_EVK_20F is a stepper motor driver evaluation kit. It is a low-cost board enabling fast evaluation of ROHM stepper motor BD6425EFV IC and easy prototyping of real applications. The kit consists of a stackable shield for Arduino Uno board and a software library to manage the stepper motor driver IC. The EVK can be used as well standalone providing power supply and appropriated input signals. This EVK supports microstep, high voltage with CLK-IN (clock input) control stepper motor driver BD6425EFV IC.
It integrates PWM constant-current drive with adjustable decay ratio and the ability for full, half and microstepping. The IC features single supply operation by integrating voltage regulator for the low power logic together with highly efficient DMOS output power stages. The motor driver integrates ghost supply prevention, thermal shutdown, over-current protection, under/over voltage lockout high ESD resistance and pin short protection for robust and reliable operation.
These products are a low power consumption PWM constant current-drive driver of bipolar stepping motor with power supply’s rated voltage of 45V and rated output current of 1.0A, 1.5A.
Applications:
a. serial dot impact printer
b. sewing machine etc.
