TB6548F/FG
Three-Phase Full-Wave PWM Sensorless Controller for Brushless DC Motors
The TB6548F/FG is a three-phase full-wave sensorless controller
for brushless DC motors. The device supports voltage control by
PWM signal input and is capable of PWM type sensorless driving
when used in conjunction with the TA84005F/FG.
Features
• Three-phase full-wave sensorless drive
• PWM control (PWM signal is supplied from external sources)
• Turn-on signal output current: 20 mA
• Built-in protection against overcurrent
• Forward/reverse modes
• Built-in lead angle control function (0, 7.5, 15 and 30 degrees)
• Built-in lap turn-on function
Weight: 0.32 g (typ.)
