L298N Datasheet, PDF

The L298N is a dual H-bridge motor driver IC commonly used for controlling DC and stepper motors. However, it has limitations such as significant power loss due to its bipolar junction transistor (BJT) design, leading to inefficiencies and heat generation. Several modern alternatives offer improved performance:
