FT3107T Three Phase Sensorless BLDC Motor Controller

The FT3107T is a Three Phase sensorless BLDC Motor controller. It provides several drive modes (BLDC, Pseudo-BLDC, Pseudo-SINE, Narrow BLDC) with constant/variable lead angle intended for a wide range of motor characteristics. Open/Closed loop speed adjustment can be achieved through either direct-PWM or analog voltage or frequency control, initiated by soft.
