L293D Motor Driver Shield in Pakistan

L293D is a monolithic integrated, high voltage, high current, 4-channel driver.Basically this means using this chip you can use DC motors and power supplies of up to 36 Volts, thats some pretty big motors and the chip can supply a maximum current of 600mA per channel, the L293D chip ( L298N Datasheet) is also what’s known as a type of H-Bridge. The H-Bridge is typically an electrical circuit that enables a voltage to be applied across a load in either direction to an output, e.g. motor.

The L293D is designed to provide bidirectional drive currents of up to 600-mA• High-Noise-Immunity Inputs at voltages from 4.5 V to 36 V. Both devices are • Output Current 1 A Per Channel (600 mA for designed to drive inductive loads such as relays, L293D) solenoids, DC and bipolar stepping motors, as well as • Peak Output Current 2 A Per Channel (1.2 A for other high-current/high-voltage loads in positiveL293D) supply applications.

L293D Motor Driver Shield in Pakistan Specifications:

1. Can drive 4 DC motors or 2 stepper motors or 2 Servo
2. Up to 4 bi-directional DC motors with individual 8-bit speed selection
3. Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil or interleaved stepping.
4. 4-H-Bridges: per bridge provides 0.6A (1.2A peak current) with thermal protection, can run motors on 4.5V to 36V DC
5. Pull down resistors keep motors disabled during power-up
6. Include reset button
7. 2-external terminal power interface, for separate logic/motor supplies
8. Tested compatible for Arduino Uno, Mega

Application Information:

A typical application for the L293 device is driving a two-phase motor. Below is an example schematic displaying how to properly connect a two-phase motor to the L293 device. Provide a 5-V supply to VCC1 and valid logic input levels to data and enable inputs. VCC2 must be connected to a power supply capable of supplying the needed current and voltage demand for the loads connected to the outputs.
