Product Summary

The TB6575FNG is a 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.

Parametrics

TB6575FNG absolute maximum ratings: (1)Power supply voltage VDD: 5.5 V; (2)Input voltage Vin: -0.3 to VDD + 0.3 V; (3)Turn-on signal output current IOUT: 20 mA; (4)Power dissipation PD: 780 mW; (5)Operating temperature Topr: -30 to 105℃; (6)Storage temperature Tstg: -55 to 150℃.

Features

TB6575FNG features: (1)3-phase full-wave sensorless drive; (2)PWM chopper drive; (3)PWM duty cycle control by analog input; (4)20-mA current sink capability on PWM output pins; (5)Overcurrent protection; (6)Forward/reverse rotation; (7)Lead angle control (7.5° and 15°); (8)Overlap commutation; (9)Rotation speed sensing signal; (10)DC excitation mode to improve startup characteristis; (11)DC excitation time and forced commutation time for startup operation can be changed.; (12)Forced commutation frequency can be selected. (fXT/(6 × 216), fXT/(6 × 217), fXT/(6 × 218) ); (13)Output polarity switching (P-channel + N-channel, N-channel + N-channel) .
