TB6548F is a 3-phase full-wave sensorless controller for brushless DC motors produced by Toshiba Corporation. It can control voltage by PWM signal input and has overcurrent protection and forward/reverse functions.
The Toshiba TB6548F is a silicon monolithic 3-phase full-wave sensorless controller designed for brushless DC (BLDC) motors. It operates by controlling voltage through external PWM signal inputs and supports various drive modes, including lap turn-on and lead angle control.
Key features include built-in protection against overcurrent, the ability to switch between forward and reverse rotation modes, and a built-in lead angle setting function offering 0, 7.5, 15, or 30 degrees. The device is intended for use in general electronics applications such as industrial robotics and domestic appliances.
