Working Principles

The S-L2980A44PN-TF-G is based on the H-bridge topology, which allows bidirectional control of DC motors. It utilizes power MOSFETs as switching elements to regulate the current flow through the motor windings. The control signals provided to the inputs (IN1A, IN1B, IN2A, IN2B) determine the direction and speed of the motor rotation. The enable inputs (EN1, EN2) activate or deactivate the respective motor channels. The sense voltage inputs (VSENSE1, VSENSE2) provide feedback on the motor current for protection and monitoring purposes.

Detailed Application Field Plans

• Robotics: Control of robot arm actuators, wheeled or legged robot locomotion
• Automotive: Electric power steering, window regulators, seat adjustment
• Industrial Automation: Conveyor belt control, CNC machine axis control
• Home Appliances: Washing machine drum rotation, dishwasher spray arm control
• Medical Devices: Surgical robot joint control, infusion pump motor control
