The DPY50001 is a single-axis 5A bipolar microstep motor driver and a 125W power supply enclosed in a package. The DPY50001’s microstep driver has an output current capability of 0.5 Amps minimum to 5.0 Amps maximum (Peak Rating). The inputs are optically isolated with a minimum sourcing of 1.0mA per input (+3.5VDC minimum to +24VDC maximum). The clock input is set to receive either positive or negative edge clocks with a maximum frequency of 400kHz. The driver offers direction control and motor current ON/OFF capabilities. The Reduce Current Enabled automatically reduces motor current to 50% of set value after the last step is made (20msec delay). The driver has built-in features to indicate power on (Green LED), a fault condition (Red LED) and clocks being received. (Yellow LED)

With the DPY50001, various step resolutions can be implemented by the onboard dip switch. These divisions range from 200 steps per revolution to 12,800 steps per revolution. The bipolar driver configuration handles 4, 6 and 8 lead motors. Protection devices have been added to this driver for Phase to Phase Short-Circuit and Motor Miss-Wire conditions.
