DESCRIPTION
Two drive modes are provided, namely SBLDC (quasi-sine-wave) modulation or BLDC (120°). Speed can be controlled either by setting the closed speed reference directly or through the adjustment of PWM duty cycle linearly proportional to the output speed. 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 FT3103 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. Feature● Position sensorless BLDC controller
