The TB6575FNG(O,C,8,EL) is a PWM Sensor-less Controller provides sensor-less commutation and PWM current control for 3-phase full-wave BLDC motors. It controls rotation speed by changing a PWM duty cycle by analogue voltage and it is a silicon monolithic CMOS integrated circuit.
PWM chopper drive
Over-current protection
Forward/reverse rotation
Overlap commutation
Rotation speed sensing signal
DC excitation mode to improve start-up characteristic
DC excitation time and forced commutation time for start-up operation can be changed
