Drive modules use TipsDriver module range of applications The L298N is the ST Company production of a high-voltage, high-current motor driver chips. The chip uses a 15-pin package. The main features are: high operating voltage, the maximum operating voltage of up to 46V; Output current instantaneous peak current up to 3A continuous operating current of 2A; rated power of 25W. Contains two H-bridge high voltage and high current full-bridge driver can be used to drive a DC motor and stepper motor, relay coil inductive load; using standard logic level signal control; having two enable control end allow or prohibit the work has a logic device power supply input terminal, in the case regardless of the input signal affect the internal logic circuit portion to operate at a low voltage; can be an external sense resistor, the amount of change in feedback to the control circuit. The L298N chip drive motor, the chip can drive two-phase stepper motors or four-phase stepper motor can drive two DC motors.

Circuit schematic diagram

This module integrates a built-in 5V power supply. When you drive voltage of 7V-35V can onboard 5V logic supply, do not input voltage when using onboard 5V power supply, the +5 V power supply interface, but leads to 5V voltage for external useWhen ENA so IN1 IN2 control OUT1 OUT2When ENB so IN3 IN4 control OUT3 OUT4

Application examples1: drive stepper motorDrive ordinary 4-wire 2-phase motor connection, as shownEnable ENA ENBFrom IN1 - IN4 enter the following drive timing, you can control the speed and direction of the stepper motor

2: drive DC motorThis module is a 2-channel H-bridge driver can drive two motors at the same time, the connection shown in Figure shownSo can ENA ENBRespectively, from the speed and direction of the input to the PWM signal driving the motor 1 on IN1 IN2The PWM signal of the speed and direction of the drive motor 2 can be respectively from IN3 IN4 inputSignal as shown
