The L293 is limited to 600 mA, but in reality can only handle much small currents unless you have done some serious heat sinking to keep the case temperature down.

Enable pins 1 and 9 (corresponding to the two motors) must be high for motors to start operating. http://www.me.umn.edu/courses/me2011/arduino/technotes/dcmotors/L293/L293.html
Pin 1 is at the top left when the notch in the package faces up. About STMicroelectronics Who We Are Management ST Code of Conduct Blog Media Center Newsroom Backgrounders Media Contacts Media Subscription Investor Relations Investor Relations Home Calendar & Presentations Quarterly Results Corporate Governance For driving the motor with left H-bridge you need to enable pin 1 to high. L293d will use this to drive the motor.
Available from mouser.com, Mouser part number 595-SN754410NE, $1.88. Remember that L293 IC can drive only 0.5A per channel (for each motor).Liamthe1st (author)Reply2015-08-17I am a in UK a full Member Pro etcLiamthe1st (author)Reply2015-08-17for some reason down load PDF is not Additionally, the L293E has external connection of sensing resistors, for switchmode control. L293d Motor Driver Pin Diagram Here is a table describing the control pin functions.
I mean, there is no available stock of the said IC and im going to use it im project arduino and bluetooth car. Will post an instructable soon!Aadhil Rafeek (author)Reply2015-11-10Great tutorial!!!yousifhobelos (author)Reply2015-09-23Hello brother !!Here im trying to build a cnc devices , somehow i use the same motor driver ..s i decided to use This is handy because you could run one bidirectional motor and two relays using just 4 Arduino pins and a single L293. http://www.rakeshmondal.info/L293D-Motor-Driver You can use it to control small dc motors - toy motors.
L293D Pin Diagram Working of L293D There are 4 input pins for l293d, pin 2,7 on the left and pin 15 L293d Stepper Motor Driver This means that if your motors need more than 5V, you should power this pin with that amount of voltage, and the rest of the circuit with 5V.Step 3: Arduino Code// It means if you want to operate a motor at 9V then you need to provide a Supply of 9V across VSS Motor supply. Please contact our sales support for information on specific devices.
L293D Logic Table. Thank you!

L293d Motor Driver Module Runs at 5V logic.
Pin 1 and pin 9, for being able to drive the motor, the pin 1 and 9 need to be high. http://vinaprosoft.com/motor-driver/l293d-motor-driver-circuit.php since i only need them to run in one direction, i can use all positive pins available while sending all the negatives from the motors together.. A more recent, improved specification, pin-for-pin compatible chip is recommended for new designs: the TI SN754410NE motor driver. Thank you! L293d Motor Driver Board
Thanks! narnian (author)comodoreReply2009-05-01Any of the microcontrollers whether PIC or AVR can do this. Controlling a DC Motor Drive a DC motor forward and in reverse with variable speed Adafruit's Raspberry Pi Lesson 10. http://vinaprosoft.com/motor-driver/l298-dc-motor-driver-circuit.php I have the same exact one.
Concept It works on the concept of H-bridge. L293d Pin Diagram Sometimes it can be extremely hot.In this tutorial you will learn how to use it with Arduino uno to control two dc motors.Step 1: What You Will NeedShow All ItemsFor this Logic 01 and 10 will rotate it in clockwise and anticlockwise directions, respectively.
VCC pin 16 is the voltage for its own internal Operation. They do take a little more diy to use, because the breakout boards sold on the internet are terrible, and you can make one much smaller, cheaper, and funner with a Key Features OVERTEMPERATURE PROTECTION OUTPUT CURRENT 1A PER CHANNEL INHIBIT FACILITY PEAK OUTPUT CURRENT 2A PER CHANNEL (non repetitive) SEPARATE LOGIC SUPPLY HIGH NOISE IMMUNITY Circuit Diagram Download Resources Quick Links L293d Ic Price The following schematic shows how to connect the L293 to your motor and the Arduino.

Motor drivers act as current amplifiers since they take a low-current control signal and provide a higher-current signal. this contact form So, is there other value of IC as replacement for it.?
ITP Physical Computing has a terrific tutorial on using an Arduino and an L293 to control a bi-directional motor. I would save much space... Using an Arduino Leonardo as MCU.DanM5 (author)Reply2014-09-20Thanks for the post. I just burns my 2 L293D ic's, yeah its heat up during I am controlling my Car, I am using NI -CD 8 AA 700mAH 9.6 V Battery, the positive of
Hook up the circuit and run your motor while keeping your finger on the chip. And that's it, you've programmed your Arduino board!You can keep playing with that by clicking the "Edit" button and start making your own modifications to the code. When I check the current flowing through a single motor with a multimeter, it peaks at about 80mA for the given script and upwards of 160mA with continuous use. Area of interest?
The pinout for the L293 in the 16-pin package is shown below in top view. Small means small. For this reason, they may not be 100% accurate for a specific device. The L293 ground goes to both the battery minus and the Arduino GND.
Assume you have only one motor connected with the enable tied to Arduino Pin 3, and the two direction controls tied to Arduino Pins 4 and 5. But you have to check first your motors specs! If it gets too hot to touch, you can't use it with your motor. (Note to ME2011 students: The L293 should be OK for your small motor but is not OK It can supply a max current of 600mA per channel.Since it can drive motors Up to 36v hence you can drive pretty big motors with this l293d.
Eirinn (author)comodoreReply2009-05-06I will answer you honestly; i don't know. I try to download it as pdf and is working fine on my pc... Input logic 00 or 11 will stop the corresponding motor. I made this circuit and it worked well.
