5. Positional Variation
Positional signal
occurs in connection with the frequency of the PWM signal. Take particular care if using the IC for
high-speed motors.
PWM signal
Output voltage
of the
TA84005F/FG
Since positional detection is performed in synchronization with the PWM signal, positional variation
Variation is calculated by detecting at two consecutive rising edges of the PWM signal.
