Note:
1. RC coupling at each input (parts shown dotted) might change depending on the PWM control scheme used in the application and the wiring impedance of the application's printed circuit board. The SPM input signal section integrates 3.3k (typ.) pull-down resistor. Therefore, when using an external filtering resistor, please pay attention to the signal voltage drop at input terminal. 2. The logic input is compatible with standard CMOS or LSTTL outputs.

Note:
1. To avoid malfunction, the wiring of each input should be as short as possible. (less than 2-3cm) 2. VFO output is open collector type. This signal line should be pulled up to the positive side of the 5V power supply with approximately 4.7k resistance. Please refer to Figure 8. 3. VFO output pulse width should be determined by connecting an external capacitor(CFOD) between CFOD(pin7) and COM(pin2). (Example : if CFOD = 33 nF, then tFO = 1.8ms (typ.)) Please refer to the note 6 for calculation method. 4. Input signal is High-Active type. There is a 3.3k resistor inside the IC to pull down each input signal line to GND. When employing RC coupling circuits, set up such RC couple that input signal agree with turn-off/turn-on threshold voltage. 5. To prevent errors of the protection function, the wiring around RSC, RF and CSC should be as short as possible. 6. In the over current protection circuit, please select the RFCSC time constant in the range 3~4 s. 7. Each capacitor should be mounted as close to the pins as possible. 8. Relays are used at almost every systems of electrical equipments of home appliances. In these cases, there should be sufficient distance between the CPU and the relays.
