FT1016 Datasheet | Fortior

` FT1016 Three Phase single Hall sinusoidal BLDC Motor controller Description The FT1016 is a Three Phase sinusoidal Brushless DC (BLDC) Motor controller. It es with the advanced single Hall sensor design. Using the single Hall sensor signals, the control system is able to execute the PWM mutation by switching the 3-Phase inverter. Due to its adaptive Features and wide power-supply range capabilities, it is intended to cover a wide range of motor characteristics, while requiring little tuning from the user. Speed adjustment can be achieved through either direct-PWM or analog voltage control. Speed indicator is provided through a Frequency Generator output (FG×3), generating digital pulse with its frequency proportional to the speed of the motor. Protection functions of FT1016 are prehensive including lock protection and automatic recovery, under voltage, thermal shutdown, current limit and over current protections. These prevent the control circuits and the motor from being damaged, particularly under stressed applications and demanding environments. Feature - Advanced single Hall design - Support space vector pulse width modulation (SVPWM) - 180°sinusoidal drive, for high efficiency and low acoustic noise - Two speed adjustment methods can be selected (direct-PWM and analog voltage control) - Lead angle control - FG (Frequency Generator) and RD (Rotation detection) output - Current limit and over current protection - Built-in lock protection and automatic recovery circuit - Built-in thermal shutdown protection (TSD) - Built-in under voltage lock out protection.
