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. • BLDC Motor or PMSM Control • Low-Noise Motor Applications • Fan, Pump, Tools, etc. Ordering Information Operating Temperature Range Package FCM8201QY -40°C to 125°C 32-Lead, LQFP, JEDEC MS-026, Variation BBA, 7 mm Square Packing Method Tray FCM8201 3-Phase Sinusoidal Brushless DC Motor Controller Typical Application Circuits VOUT DC/DC Converter VOUT VOUT 25 VPP HOVP 1 32 PGND 6 FREE/nST VSENSE 21 5 CW/CCW FCM8201 16 DUTY 7 XP 8 XN 10 DGND X 30 V 29 Y 28 11 VOUT 18 AGND 20 AS W 27 Z 26 I_IN 19 15 I_FB 14 IN 13 OPO 12 IP 23 OC_TMR 17 R_CLK HA 2 HB 3 HC 4 FO 9 nFAULT 24 RT 22 3-Phase Inverter Motor VOUT VOUT Figure Stand-Alone Application 2010 Fairchild Semiconductor Corporation FCM8201 3-Phase Sinusoidal Brushless DC Motor Controller Typical Application Circuits Continued Figure SPI Application 2010 Fairchild Semiconductor Corporation |
