Hence, H-bridge circuit using L293D ICs are perfect for driving a motor. As we know that the voltage must be change the direction of being able to rotate the DC motor in both the directions. This L293D IC works on the basic principle of H-bridge, this motor control circuit allows the voltage to be flowing in any direction. As well, this IC can drive small and quiet big motors. It means, by using a L293D IC we can control two DC motors. This IC consists of 16-pins which are used to control a set of two DC motors instantaneously in any direction. L293D IC is a typical Motor Driver IC which allows the DC motor to drive on any direction. Operation of the H-Bridge L293D Motor Driver IC The table below gives the different operations with the four switches corresponding to the above circuit.

Or let the motor run free to a stop, when the motor is detached from the circuit. When the motor comes to a sudden stop, as the terminals of the motor are shorted. Generally, the H-bridge motor driver circuit is used to reverse the direction of the motor and also to break the motor. By opening the switches S1 and S4 and closing the switches S2 and S3, this voltage is inverted, allowing invert operation of the motor. When the S1 and S4 switches are closed, then a +ve voltage will be applied across the motor. In specific, a bipolar stepper motor is always driven by a motor controller having two H-bridges H-Bridge CircuitДЄ H-bridge is fabricated with four switches like S1, S2, S3 and S4. These motor control circuits are mostly used in different converters like DC-DC, DC-AC, AC-AC converters and many other types of power electronic converters. H-bridge circuits are frequently used in robotics and many other applications to allow DC motors to run forward & backward. H Bridge Motor Control Circuit Using L293d IC H-Bridge CircuitДЄ H bridge is an electronic circuit that allows a voltage to be applied across a load in any direction.
