Working Principles

The BA6161N motor driver IC operates by receiving control signals through the IN1 and IN2 pins to determine the motor's direction. The speed of the motor is controlled using a PWM signal applied to the IN1 pin. The IC generates an internal frequency that can be used for motor speed detection through the FG pin. Built-in protection circuits ensure safe operation by monitoring the current and temperature, triggering shutdown if necessary.
