L293d Motor Driver Ic Pin Diagram

Hello friends this is my first instructable.
L293d motor driver ic pin diagram. A single l293d ic is capable of running two dc motors at the same time. L293d ic pin configuration. Other important l293d features are. Input 1 digital input to control the output 1.
A motor driver is an integrated circuit chip which is usually used to control motors in autonomous robots. L293d is a 16 pin ic which can control a set of two dc motors simultaneously in any direction. Pin diagram of a l293d motor driver ic controller. April 12 2019 by eg projects.
L293d motor driver ic l293d is a motor driver ic which allows the motor to drive on either direction. How to use l293d to control motors. Each output is a complete totem pole drive circuit with a darlington transistor sink and a pseudo darlington source. In case the circuit becomes complex and you need to drive load with two three or four ttl signals you use a combination of transistors or mosfet to.
As the name suggests it is mainly used to drive motors. L293d motor driver pinout diagram. The l293d is a popular 16 pin motor driver ic. Motor driver act as an interface between arduino and the motors.
It means that you can control two dc motor with a single l293d ic. Pins 4 5 12 13 of l293d are the ground pins so connect these to ground. These ics are designed to control 2 dc motors simultaneously. L293d equivalent dual timer ic.
Lb1909mc sn754410 uln2003. When ever you want to drive heavy loads with a small ttl signal you use a transistor bjt or a mosfet. Drivers are enabled in pairs with drivers 1 and 2 enabled by 1 2en and drivers 3 and 4 enabled by 3 4en. This pin is also called as a master control pin.
Ic l293d pin functions. L293d is a 16 pin ic which can control a set of two dc motors simultaneously in any direction. Connect the pin 1 of the l293d ic the pin 7 of arduino. The most commonly used motor driver ic s are from the l293 series such as l293d l293ne etc.
Where to use l293d ic. When the enable pin is high then the left part of the ic will work otherwise it won t work. L293d h bridge driver is the most commonly used driver for bidirectional motor driving applications. L293d pinout 16 pin pdip package.
Connect the pin 3 of the l293d to one end of the motor. Enable 1 2 this is an active high input. Input high state enabled. First of all we will connect the l293d motor driver ic with the arduino.
The state of all outputs out1 out2. L293 and l293d h bridge motor driver ic pin out and working. L293 and l293d are characterized for operation from 0 c to 70 c. In this instructable i have shown the use of its pins with detail amp.
When the pin is high it enables the driver channels 1 and 2. It can control two dc motors. Input low state disabled. The connections are given below.
L293d chip is a very populer ic for controlling motors via mcu.
