Working Principles

The S-L2980A54PN-TF-G is a dual H-bridge motor driver IC. It utilizes the H-bridge configuration to control the direction and speed of a motor. By applying appropriate logic signals to the input pins (IN1, IN2), the motor can be driven forward or reverse. The enable pin (EN) allows independent control of each channel. The VREF pin sets the reference voltage for motor current sensing, which can be adjusted using an external resistor. The IC also incorporates thermal shutdown and overcurrent protection mechanisms to ensure safe operation.
