Application circuit suitable for high voltage brushless DC motor fan drive

 
Overview
• Brushless motor controller IC TC78B041FNG is used for fan motor control.
• High voltage 3-phase motor driver IC TPD4204F is used for fan motor driving.
• Hall elements (HU/HV/HW) are mounted on the underside of the circuit board.

Features

• According to the fan form, the circuit board is designed into a circular hollow type.
• Brushless DC motor controller IC TC78B041FNG and high voltage 3-phase motor driver IC TPD4204F are mounted on the circuit board.
• The built-in voltage regulator circuit, protection functions, and detection functions in the IC all help simplify peripheral circuit design.
