Driver 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.
Port Function Chart
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 use
When ENA so IN1 IN2 control OUT1 OUT2
When ENB so IN3 IN4 control OUT3 OUT4
Application examples:
1: drive stepper motor
Drive ordinary 4-wire 2-phase motor connection, as shown
Enable ENA ENB
From IN1 - IN4 enter the following drive timing, you can control the speed and direction of the stepper motor
