IC IC UCN5804 is designed specifically for the purpose of stepper motor drivers. Stepper motor driver IC UCN5804 with this very simple and uses only 2 additional components as current-limiting resistors which flows into the stepper motor, it also can be removed so that the stepper motor driver is a pure IC UCN5804 only use only. UCN5804 IC can be used for stepper motor driver with 5-20VDC voltage. Source voltage required for a series of stepper motor driver IC dengn this UCN5804 follow steppernya motor voltage. Picture a series of stepper motor driver ICs with UCN5804 in detail can be seen in the following figure.
Drive Stepper Motor circuit UCN5804
In the series of stepper motor drivers with IC UCN5804 above to run a DC motor takes 2 inputs ie, the input signal and the input logic stepper direction of rotation. The input signal is a pulse stepper with a certain frequency where the frequency of these pulses that determines the speed of stepper motor puter. Then the input logic is a stepper motor rotating direction input logic 0 and 1 that is given to the IC UCN5804 to adjust the stepper motor rotating direction.
