This driverIC outputs the FG signals forsome special applications. For FG application, the driver lC will g en e rate square wave to indicate the motor rotation frequency. According to the motorinternal structure, the pole number is different for different motors. The FG will output the real motor's rotation frequency by dividing the pole number (must be adjusted underIC process).
