Motor Driver H-Bridge L293 module:
The L293D is a device formed in the shape of H. This called as a Quadruple high-current half-H bridge driver. This designed to drive the motors as well as any devices in both directions. They drive current up to 600mA and voltage from 5 V to 36 V. This used to drive two or four DC motor driver or dual stepper motor driver. To reduce dissipation separate supply given. This board contains L293D IC.
Dual H-Bridge motor driver integrated circuit (IC) is L293D. This driver acts as Current amplifiers as they take low current moreover provide a higher current. This used to drive the Motors.
This module contains two inbuilt H-Bridge driver circuits. The H bridge circuit contains 4 switches. This used to drive two motors simultaneously, both in forward and reverse direction. The motor controlled by input logic at 2 & 7 and 10 & 15 pins. Logic 00 or 11 will stop the motors. The other two logic performs the clockwise and anti-clockwise direction action. The output is complete TTL logic, with a pair of transistor sink and a source.
The driver module enabled in pairs, with drivers 1 and 2 enabled by 1,2 “EN” pins and drivers 3 and 4 enabled by 3,4 “EN” pins. If the enable pins are high, a corresponding motor actuated. Their output of the motor is HIGH and they are in phase with the input. If “EN” is low, the output is OFF.
This driver especially used to amplify the required current to the motor. In general, Microprocessors cannot provide sufficient current to the motor. So, they will add the driver with the circuit.
