Motor drivers behave as amplifiers since they supply a higher-current signal and take a control signal. This greater sign is utilized to drive the motors.
L293D contains two driver circuits that are inbuilt. In its mode of operation, two DC motors can be driven simultaneously, both in forward and reverse direction. Input logic can controls. two motors' motor operations at pins 2 & 7 and 10 & 15. Logic 00 or 11 will stop the corresponding engine. 10 and logic 01 will rotate it in anticlockwise and clockwise directions.
Empower pins 1 and 9 (corresponding to the 2 motors) must be high for motors to start operating. When an enable input is high, the driver gets empowered. As a result, the outputs work with their inputs in phase and become busy. When the input is reduced, this driver is handicapped, and their outputs are off and at the high-impedance state.
