The L293D is a 16 pin IC, with eight pins, on each side, dedicated to the controlling of a motor. There are 2 INPUT pins, 2 OUTPUT pins and 1 ENABLE pin for each motor. L293D consist of two H-bridge. H-bridge is the simplest circuit for controlling a low current rated motor. Behringer x32 firmware update download.

1 - Enable 1-2, when this is HIGH the left part of the IC will work and when it is low the left part won’t work.
2 - INPUT 1, when this pin is HIGH the current will flow though output 1
3 - OUTPUT 1, this pin should be connected to one of the terminal of motor
4,5 - GND, ground pins
6 - OUTPUT 2, this pin should be connected to one of the terminal of motor
7 - INPUT 2, when this pin is HIGH the current will flow though output 2
8 - VCC2, this is the voltage which will be supplied to the motor.
16 - VCC1, this is the power source to the IC. So, this pin should be supplied with 5 V
15 - INPUT 4, when this pin is HIGH the current will flow though output 4
14 - OUTPUT 4, this pin should be connected to one of the terminal of motor
13,12 - GND, ground pins
11 - OUTPUT 3, this pin should be connected to one of the terminal of motor
10 - INPUT 3, when this pin is HIGH the current will flow though output 3
9 - Enable 3-4, when this is HIGH the right part of the IC will work and when it is low the right part won’t work.

Why 4 grounds in the IC?

Dc Motor Driver Ic

L293d Motor Driver Ic For 4 Wheels Program

The motor driver IC deals with heavy currents. Due to so much current flow the IC gets heated. So, we need a heat sink to reduce the heating. Therefore, there are 4 ground pins. When we solder the pins on PCB, we get a huge metalllic area between the grounds where the heat can be released.

Why Capacitors?

L293d Motor Driver Module

The DC motor is an inductive load. So, it develops a back EMF when supplied by a voltage. There can be fluctuations of voltage while using the motor say when suddenly we take a reverse while the motor was moving in some direction. At this point the fluctuation in voltage is quite high and this can damage the IC. Thus, we use four capacitors that help to dampen the extreme variation in current.
