SPMD150STP - STMicroelectronics

SPMD150STP 1.5 A stepper motor driver module

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.
