Controlling ICs on motor drivers like Atmega1632, 8051 or any microcontroller chip cannot draw that much current through them directly at their pinouts.If we directly connect the motors to any ICs it will burn out due to high current draw.
L298N Dc Motor Circuit Drivers Like Atmega1632To drive a motor, we just cannot connect it directly to the microcontroller. These ICs are designed to control 2 DC motors simultaneously. H-bridge is the simplest circuit for controlling a low current rated motor. L298N Dc Motor Circuit Driver Can DrawMaximum 600mA Current can be drawn through both channels of L293D whereas L298N Motor Driver can draw up to 2A from both channels. L298N Dc Motor Circuit Full H DriverL293 is a quadruple motor driver that uses a half-H driver while L298 is a dual full-H driver, i.e, in L293 all four input-output lines are independent while in L298, a half-H driver cannot be used independently, only a full H driver has to be used. As L293 output current for each channel is 650mA whereas it is 2A for L298. EMFs are provided internally in L293D but must be provided externally in L298. L293D is suitable for small current drawing motors like BO motor, DC geared motors up to 500 RPM, and small stepper motors which take less current up to 600mA at their highest torque rating. WhereasL298N has the advantage of higher output current up to 2A and therefore it is suitable for high torque and high RPM motors like Johnson motors and high torque DC Geared motors. That is, with an H-bridge, a microcontroller, logic chip, or remote control can electronically command the motor to go forward, reverse, brake, and coast. Hence you dont need to do add any controller board and interfacing wiring with a separate Arduino board. Both drivers are available in the BRUSHED DC MOTOR DRIVER category almost the same price under INR 150 to 200 bucks. So depending upon your project requirement choose the perfect motor driver.
