` FT1016
Three Phase single Hall sinusoidal BLDC Motor controller
Description
The FT1016 is a Three Phase sinusoidal Brushless DC
(BLDC) Motor controller. It comes with the advanced
single Hall sensor design. Using the single Hall sensor
signals, the control system is able to execute the PWM
commutation 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 comprehensive
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.
