Description
The SPMD150STP is a highly integrated stepper
motor driver module, that allows the user to easily
design a complete motor control system for two-
phase 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.
