Detail about L298N Dual Bridge DC Stepper Controller Control Motor Driver module

The L298 is an integrated monolithic circuit in a 15- lead Multiwatt and PowerSO20 packages. It is a high voltage, high current dual full-bridge driver de- signed to accept standard TTL logic levels and drive inductive loads such as relays, solenoids, DC and stepping motors. Two enable inputs are provided to enableordisablethedeviceindependentlyofthein- put signals. The emitters of the lower transistors of each bridge are connected together and the corre- sponding external terminal can be used for the connection of an external sensing resistor. An additional supply input is provided so that the logic works at a lower voltage.

Features

Operation supply voltage up to 46 V
TOTAL DC CURRENT UP TO 4 A
LOW SATURATION VOLTAGE
OVERTEMPERATURE PROTECTION LOGICAL ”0” INPUT VOLTAGE UP TO 1.5 V (HIGH NOISE IMMUNITY)
Using L298N as the control chip,the module has such characteristics as strong driving ability,low calorific value and strong anti-interference ability.
This module can use built-in 78M05 for electric work via a driving power supply part. But to avoid the damage of the voltage stabilizing chip, please use an external 5V logic supply when using more than 12V driving voltage.
Using large capacity filter capacitor, this module can follow current to protect diodes,and improve the reliability.
L298N is a kind of high voltage,high current motor driver chip produced by ST company.Having 15 pins as package, this chip has such features as high working voltage(maximum voltage up to 46V),large output current(instantaneous peak current up to 3A,continuous working current 2A) and 25W of rated power.Two built-in H birdge high voltage and large current full bridge drivers can be used to drive the DC motor and stepper motor,relay coil and so on.Using standard logic level signal control,it has two enable control ends.It permits or prohibites device having a logic power supply input without the impact of input signal,which enables the internal logic circuit part works at low voltage.The chip can connects to external detecting resistor to give the variations to the control circuit.Using L298N chip to drive the motor,this chip can drive a stepping motor or four phase stepping motor,and two DC motors as well.

Schematic

Application

1. Driving stepper motor

The connection of driving a common 4 line 2 phase electric motor is shown in below figure after enable ENA ENB. Input the following driving timing from IN1-IN4 then the speed and direction of the stepper motor can be controlled.

2. Driving DC motor

Because the module is drived by double H bridge,it can drive two motors simultaneously. The connecting method is shown inbelow figure after enable ENA ENB
You can imput the speed and direction of PWM signal drive motor 1 from IN1 IN2
You can imput the speed and direction of PWM signal drive motor 2 from IN1 IN2
