This invention relates to a frequency identification circuit for motor driver control, belonging to the field of motor drive control technology. The frequency identification circuit compares frequency signals with corresponding duty cycles of 1% and 99% using two comparators. The first comparator circuit amplifies the output signal of the frequency identification module and inputs it to the non-inverting terminal of the comparator. The second comparator circuit directly inputs the output signal of the frequency identification module to the inverting terminal of the comparator. When the duty cycle is less than 1% or greater than 99%, the corresponding comparator outputs a low level. The signal processing circuit uses the unidirectional conductivity of a diode to perform an OR operation on the two comparison signals. If either signal goes low, the driver enable terminal is pulled low, triggering a protection mode. This invention enables rapid identification and protection against PWM signal anomalies, effectively improving the reliability of protection for motor drivers and electric servos.
