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 3.3kΩ (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. Figure 9.

It would be recommended that the bootstrap diode, D BS, has soft and fast recovery characteristics. 2. The bootstrap resistor (R BS ) should be 3 times greater than R E(H). The recommended value of R E(H) is 5.6Ω, but it can be increased up to 20Ω (maximum) for a slower dv/dt of high-side. 3. The ceramic capacitor placed between V CC - should be over 1uF and mounted as close to the pins of the SPM as possible. Fig. 10.

To avoid malfunction, the wiring of each input should be as short as possible. (less than 2-3cm) 2. By virtue of integrating an application specific type HVIC inside the SPM, direct coupling to CPU terminals without any opto-coupler or transformer isolation is possible. 3. V FO output is open collector type. This signal line should be pulled up to the positive side of the 5V power supply with approximately 4.7kΩ resistance. Please refer to Figure C SP15 of around 7 times larger than bootstrap capacitor C BS is recommended. 5. V FO output pulse width should be determined by connecting an external capacitor(c FOD ) between C FOD (pin7) and (pin2). (Example : if C FOD = 33 nf, then t FO = 1.8ms (typ.)) Please refer to the note 5 for calculation method. 6. Input signal is High-Active type. There is a 3.3kΩ 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. 7. To prevent errors of the protection function, the wiring around R F and C SC should be as short as possible. 8. In the short-circuit protection circuit, please select the R F C SC time constant in the range 1.5~2 µs. 9. Each capacitor should be mounted as close to the pins of the SPM as possible. 10. To prevent surge destruction, the wiring between the smoothing capacitor and the P&GND pins should be as short as possible. The use of a high frequency non-inductive capacitor of around 0.1~0.22 uf between the P&GND pins is recommended. 11. 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. 12. C SPC15 should be over 1uF and mounted as close to the pins of the SPM as possible. Fig. 11. Typical Application Circuit 2005 Fairchild Semiconductor Corporation 12
