Working Principles

The A6986STR motor driver IC utilizes PWM control to regulate the motor's speed and direction. The input control signal (IN) determines the desired motor operation, while the reference voltage (VREF) sets the current limit. The IC amplifies the control signal and drives the motor through the output pin (OUT). The fault indication output (FAULT) provides feedback in case of any abnormalities or malfunctions.
