    R5, R11 and R6, R12 For Currentr 2,5A KD (R5+R6) /R6 Ud VCC/KD (VCC 5V)

    Uploaded by

    This document provides a circuit diagram for a step motor drive. It uses an LM7805 voltage regulator to provide 5V power from an input voltage to the rest of the circuit. A dual LM393 comparator is used to monitor the phase inputs and control an L298 H-bridge motor driver chip. Resistor networks R5/R6 and R11/R12 set the current limit for the motor phases driven by the H-bridge. The circuit allows bidirectional control of a step motor from external phase inputs.
