Technical Specifications
The FAN8026G3X is designed to operate from a supply voltage range of [Determine Voltage Range from Datasheet, e.g. 7V to 24V]. It includes an integrated Hall sensor amplifier to amplify the signals from external Hall sensors, which are used to determine the motor's rotor position. The device also features a PWM input for controlling the motor's speed. Overcurrent protection, locked rotor protection, and thermal shutdown are incorporated to safeguard the motor and driver from potentially damaging conditions. Detailed electrical characteristics, timing diagrams, and application circuit examples are available in the Fairchild/ON Semiconductor datasheet for the FAN8026G3X.
