3-Phase Full-Wave PWM Sensorless Controller for Brushless DC Motors
TB6548F
TB6548F is a 3-phase full-wave sensorless controller for
brushless DC motors. It is capable of controlling voltage by PWM
signal input. It is capable of PWM type sensorless driving when
used conjunction with TA84005F
Features
• 3-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.)
