Matchless L293d Motor Driver Schematic

Dual h bridge motor driver integrated circuit ic.

L293d motor driver schematic. This ic can set up motors with a voltage. The motor operation of the two motors can be controlled by input logic at pins 2 7 and 10 15. Input logic 00 or 11 will stop the corresponding motor.

Basic wiring for a l293d stepper motor driver. There are 2 input pins 2 output pins and 1 enable pin for each motor. So be careful with choosing the proper motor according to its nominal voltage and current.

L293d shield is a driver board based on l293 ic which can drive 4 dc motors and 2 stepper or servo motors at the same time. Logic 01 and 10 will rotate it in clockwise and anticlockwise directions respectively. Use a normally closed button to hold the enable pins low if you want momentary on or use a normally open if y.

The next key component of the motor shield is the 74hc595 shift register ic that extends 4 digital pins of the arduino to the 8 direction control pins. H bridge is the simplest circuit for controlling a low current rated motor. Each channel of this module has the maximum current of 1 2a and doesn t work if the voltage is more than 25v or less than 4 5v.

L293d is a dual h bridge motor driver integrated circuit ic. The motor driver shield comes with two l293d dual channel h bridge motor ics so it can individually drive up to four dc motors. L293d consist of two h bridge.

L293d is a 16 pin ic which can control a set of two dc motors simultaneously in any direction. L293d chipset provides 0 6a per bridge 1 2a peak with thermal shutdown protection 4 5v to 25v pull down resistors keep motors disabled during power up big terminal block connectors to easily hook up wires 10 22awg and power arduino reset button brought up top 2 pin terminal block to connect external power for seperate logic motor supplies tested compatible with mega. It can control two dc motors simultaneously.
