At SPS in Nuremberg ROHM Semiconductor presented its Arduino-based evaluation kit (EVK) to support the evaluation of its motor driver devices as well as to enable, facilitate and accelerate customers’ developments. Designed as a ‘shield’ to plug directly into the Arduino main board, this EVK integrates a ROHM’s HTSSOP-B28 packaged stepper motor drive IC and complements ROHM’s support ecosystem, allowing engineers to rapidly prototype their stepper motor systems.
Arduino is a widely used open-source platform. The new EVK comes in 15 different variants for ROHM’s stepper motor driver ICs– from standard, micro-step, low voltage to high voltage. This comprehensive solution covers supply voltages from 8V to 42V, enables up to 2.5A per phase, as well as micro-stepping and single- or multi-phase control of one or two stepper motors. It is ideally suited to drive bipolar stepper motors available in a wide range of supply voltages and current capabilities. It drives with CLK-IN or PARA-IN variants and provides high efficiency, easier power control and comprehensive protection functionalities in a robust and compact design, enabling accurate fine-tuning of the motor performances. Moreover, the EVK is designed to be stackable so that a second shield can be added on top to drive two motors.
The ‘easy to adapt’ kit is supplied with a software library, an extensive user guide and example programs to facilitate a rapid learning curve. Once the design is proven, engineers can move rapidly from prototype to production phases fully supported by the Bill-of-Materials (BOM) and Gerber-based PCB layouts that are provided as well.
Founded in 1958, ROHM provides LSI and discrete semiconductors characterized by outstanding quality and reliability for a broad range of markets, including automotive, industrial and consumer market via its global development and sales network. In the analog power field, ROHM proposes the suitable solution for each application with power devices such as SiC, driver ICs to maximize their performance, and peripheral components such as transistors, diodes and resistors.
