Working Principles

The BTS7960B is a dual H-bridge motor driver IC. It uses MOSFETs to control the direction and speed of DC motors or stepper motors. The enable pins (EN1 and EN2) are used to activate the respective H-bridges. The input pins (IN1, IN2, IN3, IN4) control the motor direction, while the output pins (OUT1, OUT2, OUT3, OUT4) provide the motor drive signals. The sense pins (S1, S2) monitor the motor current for overcurrent protection.
