L293d motor driver ic l293d pin diagram working and. L293d is an inexpensive integrated package which has two h. The l293d can make the dc motor go clockwise, counterclockwise, or stop by just changing the values of. Each output is a complete totempole drive circuit, with a darlington transistor sink and a pseudo darlington source. The most commonly used motor driver ic s are from the l293 series such as l293d, l293ne, etc. L293d is a 16pin ic which can control a set of two dc motors simultaneously in any direction. The l293d is a dualchannel hbridge motor driver capable of driving a pair of dc motors or one stepper motor.
The l293d is a quadruple half hbridge bidirectional motor driver ic that can drive current of up to 600ma with voltage range of 4. Hbridge motor control circuit using l293d motor driver ic. This l293d ic allows dc motor to drive on either direction. It has 16 pins and it can control two dc motors at a time. We will be referring the motor driver ic as l293d only. In this lesson, you will learn how to control both the direction and speed of a small dc motor using an arduino and the l293 motor driver chip. It means that you can control two dc motor with a single l293d ic. When ever you want to drive heavy loads with a small ttl signal you use a transistor, bjt or a mosfet. H bridge and l293d motor driver h bridge is simply a circuit that allows a voltage to be applied across a load in either direction. The l293d can drive small and quiet big motors as well. Information about l293d motor driver icin hinditech.
Drivers are enabled in pairs, with drivers 1 and 2 enabled by 1,2en and drivers 3 and 4 enabled by 3,4en. They are commonly used for controlling dc motor in moving parts of robots. Left input pins on the ic will control the rotation of a motor. Hbridge is a clever and intelligent way of controlling dc motors and drive them in either direction. You can find the code and more details about the project on. It means that you can control twodc motorwith a single l293d ic. The advantage of using dc motor is that, we can reverse the polarity of applied voltage across the load without modifying the circuit. Dc motor driver circuit uln2003 experimentcorrection l293d. The l293d is already mounted on the pdb and will control 2 dc motors or a 4wire bipolar stepper motor.
L293d is a typical motor driver or motor driver ic which allows dc motor to drive on either direction. This is lesson 15 in the learn arduino adafruit series. That means it can individually drive up to two motors making it. Hbridge is the simplest circuit for controlling a low current rated motor. The l293 and l293d are characterized for operation from 0c to 70c. L293d motor driver ic l293d motor driveric is also known as hbridge ic. H bridge motor control circuit using l293d ic the ic lm293d consists of 4ip pins where, pin2 and 7 on the left side of the ic and pin 10 and 15 on the right side of the ic. It can control the dc motors in both clockwise and anti clockwise directions. L293 and l293d h bridge motor driver ic pin out and working.
Here, the motor is connected across side and right ip for the motor on the right hand side. These ics are designed to control 2 dc motors simultaneously. Hi i am eric and with this video i gonna show you how to run drive a stepper motor with an arduino using a motor driver ic l293d. L293d hbridge driver is the most commonly used driver for bidirectional motor driving applications. 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.
