The most notable feature here is its high power supply although its input pins follow lower voltage levels. The diagram above shows an example diagram for using the L298N to drive one DC motor.
To drive the motor counter clockwise, the pin Input 1 is low while the pin Input 2 is high. To drive a motor to a direction, say, clockwise, the pin Input 1 must be high while the pin Input 2 must be low. The Enable A pin must be high to turn on the motor.
For example, if a motor is using channel A, its terminals must be connected to pins Out 1 and Out 2. This IC drives two motors through two channels, A and B. It comes in two IC packages: MultiWatt15 and PowerSO20. The L298N is an integrated circuit that follows the H-bridge concept. This is very significant especially when using an Arduino board where the 5V power source is simply not enough for two DC motors. Other Extensions: control of direction indicators, the logic part of the plate to take power interface.The other benefit of using an H-bridge is that you can provide a separate power supply to the motors.Storage temperature: -25 Deg C ~ +130 Deg C.The logical part of the operating current range: 0 ~ 36mA.The logical part of the terminal supply area Vss: +5 V ~ +7 V (can take power within the board +5 V).Driven part of the terminal supply area Vs: +5 V ~ +35 V such as the need to take power within the board, the supply area Vs: +7 V ~ +35 V.Driver: L298N Dual H Bridge DC Motor Driver IC.Using L298N made by ST company as the control chip,the module has such characteristics as strong driving ability, low calorific value and strong anti-interference ability. The L298N driver module, using ST's L298N chip can directly drive two 3-30V DC motor, and provides a 5V output interface can 5V single-chip circuitry to supply, support 3.3VMCU control, you can easily control the DC motor speed and direction, you can also control the 2-phase stepper motor, smart car essential.
