FT3107

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-start. Speed indicator is provided through a Frequency Generator output, generating digital pulse with a configurable frequency proportional to the speed of the motor.

Protection functions of FT3107T are comprehensive including lock protection and automatic recovery, thermal shutdown and current limit protections. These prevent the control circuits and the motor from being damaged, particularly under stressed applications and demanding environments.
