Fortior Tech FT3206D

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. It provides such features as start-up circuit, Pulse Width Modulation (PWM) speed control, RD FG output for different control applications, as well as protective mechanisms such as lock protection and thermal protection. FT3206D is especially suitable for silent applications such as game consoles or CPU fans. It is available in DFN3x3 - 10 package. FT3206D integrates a wide range of protection features, including lock protection and automatic recovery, thermal shutdown, etc. These prevent the control circuits and the motor from being damaged, particularly under stressed applications and demanding environments.
