Note:
1. To avoid malfunction, the wiring of each input should be as short as possible. (less than 2~3cm)
2. V
4. To prevent error of the protection function, the wiring related with R
5. In the over current protection circuit, please select the R
6. Each capacitors should be mounted as close to the SPM pins as possible.
7. 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.
8. Internal NTC thermistor can be used for monitoring of the case temperature and protecting the device from the overheating operation. Select an appropriate resistor R
9. It is recommended that anti-parallel diode(D
3. Input signal is High-Active type. There is a 5kΩ resistor inside the IC to pull down each input signal line to GND. RC coupling circuits is recommanded for the prevention of
input signal oscillation. R
