Brushless DC / Permanent Magnet Synchronous Motor - The Brushless DC (BLDC) motor is growing adoption because of its higher efficiency, lower acoustic noise and vibration, longer motor/battery life, and higher reliability. All these improvements are growing demands for consumer motor applications.

In response, Fairchild has developed the BLDC/PMSM Controller. A mixed signal integrated circuit to control variable speed, three phase Brushless DC (BLDC) and Permanent Magnet Synchronous Motor (PMSM) sensored motors.

BLDC/PMSM Controllers

FCM8201: The FCM8201 has a SPI interface to allow greater configuration control via an MCUDSP/FPGA; e.g. clock generator, PWM modes, DAC, ADC, OC Timer, Watchdog Timer, Dead Time settings, Error Amp IP, etc.

FCM8202: The FCM8202 is a stand-alone solution, no SPI port; therefore no MCU/DSP/FPGA is required. The device configuration is controlled with the I/O pin settings; delivering the same external controls as the FCM8201.

Couple the BLDC/PMSM Controller with the Smart Power Module (SPM®) motor driver for fast time-to-market and higher manufacturing reliability of your motor control applications.

Use the BLDC/PMSM Controller in discrete motor drive implementations along with Fairchild Semiconductor’s HVIC (High Voltage Integrated Circuits) gate drivers, IGBTs (Insulated Gate Bipolar Transistors), and MOSFETs.
