STEVAL-SPMD150V2 1.5 A bipolar stepper motor drive module (SPMD150STP) demonstration board Data brief Features Ready-to-use board for SPMD150STP demonstration Easy interfacing with PractiSPIN software Simulates: Normal/half-step sequence and microstepping Fast/slow decay Forward/reverse Enable Phase current selectable for acceleration/deceleration ramp, running and STEVAL-SPMD150V2 stop mode Possibility to program moving and waiting time between fast and slow decay current. The module sequences internally generates the phase sequence, RoHS compliant significantly reducing the burden on the controller. Integration of a power MOSFET stage significantly reduces both commutation and Description conduction losses. The SPMD150STP offers This STEVAL-SPMD150V2 demonstration board complete output protection against all types of is designed for evaluating the performance and short conditions. The metal package acts as an the features of the SPMD150STP module. The integrated heatsink, with no ventilation or board works in conjunction with the PractiSPIN additional components required. The metal case HW and the PractiSPIN.spmd SW, which allow also isolates the inner circuit from external the user to operate with the SPMD150STP agents, making the module suitable for operation module. in harsh environments. The SPMD150STP is part of the EASY The STEVAL-SPMD150V1 supports the following POWER series of fully integrated modules measurements and demonstrations: full/half-step, designed to drive bipolar permanent-magnet microstepping, CW/CCW, control behavior, motor stepper motors. current waveforms and measurements, movement sequences. 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. The SPMD150STP implements full/half-step and microstepping driving capability, working at a variable chopper frequency.
