TB6575FNG
PWM Sensorless Controller for 3-Phase Full-Wave BLDC Motors
The TB6575FNG provides sensorless commutation and PWM
current control for 3-phase full-wave BLDC motors. It controls
rotation speed by changing a PWM duty cycle by analog voltage.
Features
3-phase full-wave sensorless drive
PWM chopper drive
PWM duty cycle control by analog input
20-mA current sink capability on PWM output pins
Overcurrent protection
Forward/reverse rotation
Lead angle control (7.5° and 15°)
Overlap commutation
Rotation speed sensing signal
DC excitation mode to improve startup characteristic
DC excitation time and forced commutation time for startup operation can be changed.
Forced commutation frequency can be selected. (f
