The L293D IC has two power supply pins. Pin 16, VCC1, is to power the IC itself, ei., its internal logic.
How does a L293D work?
The L293D IC receives signals from the microprocessor and transmits the relative signal to the motors. It has two voltage pins, one of which is used to draw current for the working of the L293D and the other is used to apply voltage to the motors.
What are TT motors?

The L293D is designed to provide bidirectional drive currents of up to 600-mA at voltages from 4.5 V to 36 V. Both devices are designed to drive inductive loads such as relays, solenoids, DC and bipolar stepping motors, as well as other high-current/high-voltage loads in positive-supply applications.
How does an L293D work?
What is L293D module?
Description: Motor Driver – L293D Driver Module is a medium power motor driver perfect for driving DC Motors and Stepper Motors. It uses the popular L293 motor driver IC. It can drive 4 DC motors on and off, or drive 2 DC motors with directional and speed control.
What is H-bridge in L293D?
An H-Bridge is nothing but an electronic circuit. Using such a circuit, you can supply current in two directions. Thats it. The L293D is an H-Bridge with two possible outputs. Meaning, you can connect two things to it… and you can control the direction of current flow in both.

What is a motor driver?
Motor drivers acts as an interface between the motors and the control circuits. Motor require high amount of current whereas the controller circuit works on low current signals. So the function of motor drivers is to take a low-current control signal and then turn it into a higher-current signal that can drive a motor.
How many pins is L293D?
L293D has 16 Pins in total which are as follows: Pin # 1 is Enable 1 which is used to turn ON or OFF the first H-bridge. Pin # 2 is Input1, which is the first Input for Motor1. It should be connected with a Microcontroller.
Why is L293D used?
How many H bridges are there in L293D IC?
two H-bridge circuits
Single L293D IC consists of two H-bridge circuits inside which can rotate two DC motors separately.
What is enable pin in L293D?
L293D has 16 Pins in total which are as follows: Pin # 1 is Enable 1 which is used to turn ON or OFF the first H-bridge. Pin # 2 is Input1, which is the first Input for Motor1. It should be connected with a Microcontroller. Pin # 3 is Output1, which is the first Output for Motor1.
What is the difference between H-bridge and half bridge?
Often “Half-bridges” are used where you’d expect an H-Bridge. They are almost the same – but only the left (or right) part of the Bridge is already connected. (2 switches in series with their middle as output. Out of two half-bridges you can build an H-Bridge (also often referred to as Full-Bridge).
What is stall torque of a motor?
Stall torque is the torque available from a motor whose output rotational speed is zero. Motors in a stalled condition may be prone to overheating and possible damage if the current flowing under these conditions becomes higher than the maximum continuous rating.
What is TT DC motor?
How to use l293d?
As you read above L293d has multiple featured and usage where it can be used without any limitations. Here is an example of the circuit of street racing cars. We just need to use two L293d to control the car. Connect all the enable pins together and use the single button to control the motor power state.
What is the l293d motor driver integrated circuit?
L293D is a dual H-bridge motor driver integrated circuit (IC). Motor drivers act as current amplifiers since they take a low-current control signal and provide a higher-current signal.
