L293D MOTOR DRIVER IC & PROJECT
L293D MOTOR DRIVER IC L293D IC is known as a motor driver . It is a low voltage operating device. It provides a high voltage to the motor unlike other IC’s. L293D provides the continuous bidirectional Direct Current to the Motor. The Polarity of current can change at any time without affecting the whole IC or any other device in the circuit. L293d has an internal H-bridge installed for two motors. H-Bridge is an electrical circuit that enables the load in a bidirectional way. It could control any DC motor speed and direction with a voltage range of 4.5 – 36 Volts . Its diodes also save the controlling device and IC from back EMF. To control the max 600mA amount of current an internal “Darlington Transistor Sink” installed in it, which could be used to control a large amount of current by providing a small amount of current. It has also internal “pseudo-Darlington source” which amplifies the input signal to control the high voltage DC motor without any interception. ADVANTAGES OF
