L298N is a high voltage, high current motor driver chip. The chip uses 15-pin package. The main features are: high voltage, maximum operating voltage up to 46V; output current, instantaneous peak current up to 3A, continuous operating current of 2A; rated power 25W. Contains two H-bridge high-voltage and high current full-bridge driver can be used to drive DC motors and stepper motors, relays, coils and other inductive load; using standard logic level signal control; having two enable control terminal, in allows input signal without being affected or disable the device has a logic supply input, the internal logic circuit part of the work at a low voltage; can be an external sense resistor, the amount of change back to the control circuit. Drive motor using L298N chip, the chip can drive a two-phase stepper motors or four-phase stepper motor, can drive two DC motors.
