Rohmопорное решение

This evaluation board 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.

This EVK supports a variety of pin-compatible ROHM stepper motor driver ICs from standard, microstep, low voltage and high voltage families with CLK-IN (clock input) or PARA-IN (parallel input) control. They integrate PWM constant-current drive with adjustable decay ratio and the ability for full, half and microstepping.

The ICs feature single supply operation by integrating the voltage regulator for the low power logic together with highly efficient DMOS output power stages. These do not require an internal charge pump so the motor drivers achieve low EMI performance. The motor drivers integrate various protection functions such as Ghost Supply Prevention (GSP), Thermal Shutdown (TSD), Over-Current Protection(OCP), Under / Over Voltage Lockout (UVLO /OVLO) high ESD resistance and Pin Short Protection for robust and reliable operation.
