L293 Motor Driver Datasheet


The maximum voltage for VSS motor supply is 36V. 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 In a single L293D chip there are two h-Bridge circuit inside the IC which can rotate two dc motor independently. This is handy because you could run one bidirectional motor and two relays using just 4 Arduino pins and a single L293. have a peek here

Addthe suffix TR to device type (e.g., L293DWPTR). Each motor takes 3 Arduino pins. (See notes below for a two Arduino pin solution.) If you are only using one motor, leave L293 pins 9, 10, 11, 12, 13, 14, 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. ITP Physical Computing has a terrific tutorial on using an Arduino and an L293 to control a bi-directional motor.

L293d Arduino

TIP: Don’t Exceed the Vmax Voltage of 36 volts or it will cause damage. The L293 is simplest and inexpensive for low current motors, For high current motors, it is less expensive to build your own H-bridge from scratch. logic diagram ÁÁ ÁÁ ÁÁ ÁÁ ÁÁ ÁÁ ÁÁ ÁÁ ÁÁ ÁÁ  217109153611141A1,2EN2A3A3,4EN4A1Y2Y3Y4Y schematics of inputs and outputs (L293) InputVCC2OutputGNDTYPICAL OF ALL OUTPUTSEQUIVALENT OF EACH INPUTVCC1CurrentSourceGND Footer MenuAboutAbout ScribdPressOur blogJoin our team!Contact UsJoin todayInvite FriendsGiftsLegalTermsPrivacyCopyrightSupportHelp / FAQAccessibilityPurchase helpAdChoicesPublishersSocial MediaCopyright © 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.

Input logic 00 or 11 will stop the corresponding motor. L293d Stepper Motor Driver The L293 ground goes to both the battery minus and the Arduino GND.

Due its size it is very much used in robotic application for controlling DC motors. L293d Wiki The l293d can drive small and quiet big motors as well, check the Voltage Specification at the end of this page for more info. Motor drivers act as current amplifiers since they take a low-current control signal and provide a higher-current signal. http://www.rakeshmondal.info/L293D-Motor-Driver Password * Enter the password that accompanies your e-mail.

It means that you can control two DC motor with a single L293D IC. L293d Motor Driver Board It’s like a switch. It means if you want to operate a motor at 9V then you need to provide a Supply of 9V across VSS Motor supply. 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.

L293d Wiki

Data sheet (PDF file, 172Kb). The L293 has an automatic thermal shutdown which means the chip will stop working if it gets too hot. L293d Arduino When the enable input is low, those drivers are disabled andtheir outputs are off and in the high-impedance state. L293d Circuit Circuit Diagram For l293d motor driver IC controller.

Here is a table describing the control pin functions. Bothdevices are designed to drive inductive loads suchas relays, solenoids, dc and bipolar steppingmotors, as well as other high-current/high-voltageloads in positive-supply applications.All inputs are TTL compatible. L293d Price

You can Buy L293D IC in any electronic shop very easily and it costs around 70 Rupees (INR) or around 1 $ Dollar (approx Cost) or even lesser cost. Area of interest? Available from mouser.com, Mouser part number 595-SN754410NE, $1.88. http://vinaprosoft.com/motor-driver/l293-secret-motor-driver.php For rotating the motor in clockwise direction the input pins has to be provided with Logic 1 and Logic 0. • Pin 2 = Logic 1 and Pin 7 = Logic

Small means small. L293d Pin Diagram Picture Upload picture Your virtual face or picture. Pin 1 and pin 9, for being able to drive the motor, the pin 1 and 9 need to be high.

H-bridges can be built from scratch with bi-polar junction transistors (BJT) or with field effect transistors (FET), or can be purchased as an integrated unit in a single integrated circuit package

Similarly, when the enable input is low, that driver is disabled, and their outputs are off and in the high-impedance state. Pin Diagram:Pin Description:  Pin No Function Name1Enable pin for Motor 1; active highEnable 1,22Input H-bridge is a circuit which allows the voltage to be flown in either direction. Logic 01 and 10 will rotate it in clockwise and anticlockwise directions, respectively. L293d Motor Shield Skip to main content RON ROBOTICS A personal website for Microcontrollers, Robotics, electronics and much more.

For driving the motor with left H-bridge you need to enable pin 1 to high.

Note that the names for pin functions may be slightly different than what is shown in the following diagrams. this contact form Given below is the pin diagram of a L293D motor controller.

VCC pin 16 is the voltage for its own internal Operation. Put your finger on top of the L293 when running the motor to see if it is getting too hot. A more recent, improved specification, pin-for-pin compatible chip is recommended for new designs: the TI SN754410NE motor driver. Hook up the circuit and run your motor while keeping your finger on the chip.

Production processing does not necessarily include testing of all parameters. You can find the necessary pin diagram, working, a circuit diagram, Logic description and Project as you read through. The L293 is made by several companies. Drivers are enabled in pairs, with drivers 1 and 2 enabled by 1,2EN anddrivers 3 and 4 enabled by 3,4EN.

Concept It works on the concept of H-bridge.

In its common mode of operation, two DC motors can be driven simultaneously, both in forward and reverse direction.
