Additional Details

The TC78B002FNG typically uses a PWM (Pulse Width Modulation) signal to control the motor speed. By varying the duty cycle of the PWM signal, the average voltage applied to the motor can be adjusted, allowing for precise speed control. The built-in protection circuits are essential for ensuring reliable operation, especially in demanding applications where the motor may be subjected to overloads or other abnormal conditions. The device is available in surface-mount packages.
