The DT5045/8080 stepper motor driver is a high-performance high-precision stepper motor driver with excellent performance, high speed and large torque output, low noise, low vibration and low heat generation. It is especially suitable for OEM customers with large-scale applications. DT drivers can select operating current and subdivision through rotary switches. There are 8 subdivision and 8 current options. It has over-voltage, under-voltage, phase current and bus over-current protection, and the input and output control signals all adopt optical isolation.
