描述 Description

FCM8201 is a three-phase sinusoidal brushless DC (BLDC) motor controller. It comes with the advanced Hall sensor design. Using the Hall sensor signals, the control system is able to execute the PWM commutation by switching the three-phase inverter. There are two PWM modes for selection: Sine-Wave Mode and the Square-Wave Mode. Square-Wave Mode includes PWM-PWM and PWM-ON approaches to improve the efficiency of the motor drive. Protection functions including over-voltage, over-current, over temperature, and short circuit prevent the control circuits and the motor from being damaged, particularly under stressed applications and demanding environments. Information about voltage, current, and temperature is accessible through the SPI interface.
FCM8201 can be operated stand-alone or worked with microcontrollers for advanced BLDC motor control.
