Pin connection when the forward/reverse switching function of NJW4303 is not used

Motor ICsHow to use

If the forward/reverse switching function is not used and no dead time is required, it is not necessary to connect a capacitor to the FRC pin, which determines the dead time during rotation switching. However, since the FRC pin is high-impedance, external noise may cause malfunctions. Connecting 1pF or more capacitor to FRC pin is recommended.
