Working Principles

The BTS7960P is a combination of power MOSFETs and a pre-driver IC, designed to provide efficient motor control. It operates based on the H-Bridge configuration, allowing bidirectional control of motors. The inputs (IN1 and IN2) determine the direction of rotation, while the enable pin (EN) activates or deactivates the motor. The integrated overcurrent protection monitors the current flowing through the motor and triggers a shutdown if it exceeds the set threshold. The thermal shutdown feature prevents the driver from overheating.

Detailed Application Field Plans

The BTS7960P is widely used in various applications that require precise and powerful motor control. Some common application fields include: - Robotics: Controlling robot movements with high precision and power. - Electric Vehicles: Driving electric vehicle motors efficiently and safely. - Industrial Automation: Operating heavy machinery and equipment. - Home Appliances: Controlling motors in appliances like washing machines and vacuum cleaners. - RC Models: Providing reliable motor control in remote-controlled models.
