Bidirectional motor control (driver) circuit for Robotics beginners


Posted on Feb 5, 2014

How can we rotate a DC motor in clockwise and anti clockwise directions Or how can we rotate a motor in forward and reverse direction These are the popular question asked by many of the robotic beginners. DC Motor (control) driver circuits are the essential circuit of robotics workshop. L293D IC is widely used for implementing DC motor control c

ircuits. It is a dual H bridge motor driver IC, that is it can drive two DC motor simultaneously and is available in 16 pin DIP package. We have already posted H Bridge motor driver circuit with transistors. L293 driver IC has a current capacity of 600mA per channel and a wide supply voltage range (4. 5 to 36V DC). They are integrated with internal high speed clamp diodes for inductive spike protection. Other superior features of L293 are high noise immunity, internal ESD protection, thermal shutdown and separate input supply for each channel.
