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.
Applications
ƒ BLDC Motor Control
ƒ Low-Noise Motor Applications
ƒ Fan, Pump, Tools, etc.
