L293d Motor Driver Circuit Diagram Pdf

Common DC gear head motors need current above 250mA. There are many integrated circuits like ATmega16,. But, IC 74 series cannot supply this amount of current. When the motor is directly connected to the o/p of the above ICs then, they might damaged. To overcome this problem, a motor control circuit is required, which can act as a bridge between the above motors and ICs ().

That could be feeding back into the circuit (thanks macegr!) What if I need more than 600mA per motor? You can subsitute SN754410's (at your risk) or piggyback solder some more L293D drivers on top of the existing ones. What pins are not used on the motor shield? This tutorial is for the now ancient V1 Motor shield.

There are various ways of making H-bridge motor control circuit such as using transistor, relays and using L293D/L298. H Bridge Motor Control Circuit Using L293d IC H-Bridge Circuit A H bridge is an electronic circuit that allows a voltage to be applied across a load in any direction. H-bridge circuits are frequently used in robotics and many other applications to allow DC motors to run forward & backward. These motor control circuits are mostly used in different converters like DC-DC, DC-AC, AC-AC converters and many other types of. In specific, a bipolar stepper motor is always driven by a motor controller having two H-bridges H-Bridge Circuit A H-bridge is fabricated with like S1, S2, S3 and S4. When the S1 and S4 switches are closed, then a +ve voltage will be applied across 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.

Generally, the H-bridge motor driver circuit is used to reverse the direction of the motor and also to break the motor. When the motor comes to a sudden stop, as the terminals of the motor are shorted. Or let the motor run free to a stop, when the motor is detached from the circuit. The table below gives the different operations with the four switches corresponding to the above circuit.

Operation of the H-Bridge L293D Motor Driver IC L293D IC is a typical Motor Driver IC which allows the to drive on any direction. This IC consists of 16-pins which are used to control a set of two DC motors instantaneously in any direction.

It means, by using a L293D IC we can control two DC motors. As well, this IC can drive small and quiet big motors. Pin Diagram of a L293D Motor Driver IC Controller L293D IC Pin Configuration • Pin-1 (Enable 1-2): When the enable pin is high, then the left part of the IC will work otherwise it won’t work.

This pin is also called as a master control pin. • Pin-2 (Input-1): When the input pin is high, then the flow of current will be through output 1 • Pin-3 (Output-1): This output-1 pin must be connected to one of the terminals of the motor • Pin4 &5: These pins are ground pins • Pin-6 (Output-2): This pin must be connected to one of the terminals of the motor. • Pin-7 (Input-2): When this pin is HIGH then the flow of current will be though output 2 • Pin-8 (Vcc2): This is the voltage pin which is used to supply the voltage to the motor. • Pin-16 (Vss): This pin is the power source to the integrated circuit.

• Pin-15 (Input-4): When this pin is high, then the flow of current will be through output-4. • Pin-14 (Output-4): This pin must be connected to one of the terminals of the motor • Pin-12 & 13: These pins are ground pins • Pin-11 (Output-3): This pin must be connected to one of the terminals of the motor. • Pin-10 (Input-3): When this pin is high, then the flow of current will through output-3 • Pin-9 (Enable3-4): When this pin is high, then the right part of the IC will work & when it is low the right part of the IC won’t work. This pin is also called as a master control pin for the right part of the IC.

H Bridge Motor Control Circuit Using L293d IC The IC LM293D consists of 4-i/p pins where, pin2 and 7 on the left side of the IC and Pin 10 and 15 on the right side of the IC. Left input pins on the IC will control the rotation of a motor. Here, the motor is connected across side and right i/p for the motor on the right hand side. This motor rotates based on the i/ps we provided across the input pins as Logic 0 and Logic 1. H-bridge Motor Circuit with L293D IC Let’s consider, when a motor is connected to the o/p pins 3 and 6 on the left side of the IC. For rotating of the motor in clockwise direction, then the i/p pins have to be provided with Logic 0 and Logic 1.

When Pin-2= logic 1 & pin-7 = logic 0, then it rotates in clockwise direction. Pin-2=logic 0 & Pin7=logic 1, then it rotates in anti clock direction Pin-2= logic 0 & Pin7=logic 0, then it is idle (high impedance state) Pin-2= logic 1 & Pin7=logic 1, then it is idle In a similar way the motor can also operate across input pin-15 and pin-10 for the motor on the right hand side.
