FT3206D Datasheet | Fortior

Overview The FT3206D is a three-phase sensorless brushless DC motor driver IC designed for low noise and low voltage applications.It drives the motor sinusoidally, giving low noise performance. The FT3206D has useful functions such as start-up circuit, Pulse Width Modulation (PWM) speed control, RDFG output for different control applications, as well as protective Features such as lock and thermal protection. FT3206D is best suited for silent applications such as game consoles or CPU fans. It is available in DFN3x310 package. Protection functions of FT3206D are prehensive, including lock protection and automatic recovery, thermal shutdown. These prevent the control circuits and the motor from being damaged, particularly under stressed applications and demanding environments.
