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. (fXT/(6 × 216), fXT/(6 × 217), fXT/(6 × 218) ) Output polarity switching (P-channel + N-channel, N-channel + N-channel)
