The L298 is an engine driver with two H-bridges. It can control two DC motors or one bipolar 4-wire stepper motor. Its main advantage is a large power supply voltage range (up to 46V) and high L298 maximum load currents: 2A continuous, 3A instantaneous.
In addition, the voltage has been applied to the CON1 connector, and the LED indicates “PWR”. LEDs2 … LED5 indicate the operation and direction of rotation of the attached motor. Starting the motor is done by supplying the logic “1” to the appropriate EN bridge of the bridge and the corresponding combination “0” and “1” to the IN1 … IN4 leads.
L298 motor driver schematic diagram
The L298 schematic diagram of the DC motor driver is shown in Figure 1. This is a typical L298 application. Schottky fast LEDs attached to the system outputs protect it from surges. The driver module is equipped with a voltage regulator 78M05 that supplies the digital part of the L298.
