STMicroelectronicsSTEVAL-SPMD150V2电源管理开发电路板和套件

This STEVAL-SPMD150V2 demonstration board is designed for evaluating the performance and the features of the SPMD150STP module. The board works in conjunction with the PractiSPIN™ HW and the PractiSPIN™.spmd SW, which allow the user to operate with the SPMD150STP module.The SPMD150STP is part of the EASY POWER™ series of fully integrated modules designed to drive bipolar permanent-magnet stepper motors.All EASY POWER modules offer an easy-to-use, fully-protected solution to implement precise position control, with high torque at rest, and without the need for external components. The module operates over a wide 12 V to 40 V input voltage range and supports an output maximum current of 1.5 A.
