Device summary Order code Description The SPMD150STP is a highly integrated stepper motor driver module, that allows the user to easily design a complete motor control system for twophase bipolar stepper motors, interfacing directly the microprocessor to the motor. The SPMD150STP is an easy-to-use fully integrated answer to motion control issues. The phase current is chopper controlled, allowing good performances and high speed. Modules offer an extensive range of protection such as overcurrent and thermal shut-down, that make it “bullet” proof as required in modern motion control systems. Metallic case allows module to operate without external heat-sink or ventilation; moreover the sealed and molded package offers a complete protection against harsh environments.
