This will double the drive current. L293D Logic Table. have a peek here
Small means small. In a single L293D chip there are two h-Bridge circuit inside the IC which can rotate two dc motor independently. TIP: Don’t Exceed the Vmax Voltage of 36 volts or it will cause damage. The L293 is designed to providebidirectional drive currents of up to 1 A at voltagesfrom 4.5 V to 36 V. https://www.engineersgarage.com/electronic-components/l293d-motor-driver-ic
Lets consider a Motor connected on left side output pins (pin 3,6). There are two Enable pins on l293d. H-bridge is a circuit which allows the voltage to be flown in either direction. All e-mails from the system will be sent to this address.
The l293d can drive small and quiet big motors as well, check the Voltage Specification at the end of this page for more info. The Twin Cities Robotics Club has an *excellent* tutorial on H-bridges, and complete detail on how to build your own $5.00 H-bridge good for several amps. The motor operations of two motors can be controlled by input logic at pins 2 & 7 and 10 & 15.

For a better experience, please download the original document and view it in the native application on your computer. L293d Motor Driver Arduino Pin 1 is at the top left when the notch in the package faces up. Motor drivers act as current amplifiers since they take a low-current control signal and provide a higher-current signal. Production processing does not necessarily include testing of all parameters.
For complete information, consult the Unitrode L293 data sheet (PDF file, 626Kb). L293d Motor Driver Wikipedia 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 Drivers are enabled in pairs, with drivers 1 and 2 enabled by 1,2EN anddrivers 3 and 4 enabled by 3,4EN. It means if you want to operate a motor at 9V then you need to provide a Supply of 9V across VSS Motor supply.
This higher current signal is used to drive the motors.L293D contains two inbuilt H-bridge driver circuits. Use these links to get more information and other versions of the L293 data sheet: Texas Instruments (who bought Unitrode) and STS Thomson (who made the original part) If the L293 L293d Motor Driver Board 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 L293d Stepper Motor Driver Active Components DSPs Development Tools Electronics Manufacturing IT Software & Hardware Micro-processors Programmable Chips (FPGAs, etc) Sensors & MEMs Test & Measurement ASICS/Custom ICs CAD/CAM/CAE Displays Electronic Product Design Opto-electronics Passive
Note that the names for pin functions may be slightly different than what is shown in the following diagrams. navigate here When an enable input is high, the associated driver gets enabled. In simple you need to provide Logic 0 or 1 across the input pins for rotating the motor. The L293D can be purchased for somewhere between $2 and $3 (quantity one) from www.mouser.com (PN 511-L293D) or www.digikey.com (PN 296-9518-5-ND). L293d Motor Driver Module
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. 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 A sample Project A sample project demonstrating the operation of L293D motor Driver IC with PIC18F4550 USB demo interface board. Check This Out It’s like a switch.
You can find the necessary pin diagram, working, a circuit diagram, Logic description and Project as you read through. L293d Motor Driver Price From the same source is a detailed tech note on PWM speed control of a motor using an H-bridge and a PIC microcontroller The L293 is an integrated circuit motor driver The L293D is designed toprovide bidirectional drive currents of up to600-mA at voltages from 4.5 V to 36 V.
A more recent, improved specification, pin-for-pin compatible chip is recommended for new designs: the TI SN754410NE motor driver. With the proper data inputs, each pair of drivers formsa full-H (or bridge) reversible drive suitable for solenoid or motor applications.On the L293, external high-speed output clamp diodes should be used Enable pins 1 and 9 (corresponding to the two motors) must be high for motors to start operating. L293d Motor Driver Pin Diagram 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.
L293D is a 16-pin IC which can control a set of two DC motors simultaneously in any direction. The L293 is made by several companies. The motors are rotated on the basis of the inputs provided across the input pins as LOGIC 0 or LOGIC 1. L293D Pin Diagram Working of L293D There are 4 input pins for l293d, pin 2,7 on the left and pin 15
