• Manufacturer: Fairchild Semiconductor

FNA41560/B2 Rev. C
Note:
1) 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
4) C
5) Input signal is High-Active type. There is a 5kW resistor inside the IC to pull down each input signal line to GND. RC coupling circuits is recommanded for the prevention
6) To prevent errors of the protection function, the wiring around R
7) In the short-circuit protection circuit, please select the R
8) Each capacitor should be mounted as close to the pins of the SPM as possible.
9) 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
10) 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.
11) The zener diode should be adopted for the protection of ICs from the surge destruction between each pair of control supply terminals. (Recommanded zener diode=24V/1W)
12) Please choose the electrolytic capacitor with good temperature characteristic in C
13) For the detailed information, please refer to the AN-9070 and FEB305-001.
