... Functional Description Power Management and Regulator FCM8201 can be operated in a wide input voltage (V range from 10V to 15V. The VOUT pin is the output terminal of an internal voltage regulator. The typical output voltage ranges between 5.0V and 5.2V. To stabilize the V circuit, add an external capacitor OUT connected closely between this terminal and the ground ...

... Sine Wave Generator FCM8201 includes space vector modulation (SVM) for the sine-wave PWM. An angle-detect circuit phase-locks the rotor position by using the Hall signals of the motor. The resolution is 32 steps per 60 degrees. Through the PWM operation, the motor current of each phase is sine-wave. The angle shift between phases is 120 degrees ...
