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) VFO output is open drain type. This signal line should be pulled up to the positive side of the MCU or control power supply with a resistor that makes IFO up to 1mA. Please refer
to Figure14.
4) CSP15 of around 7 times larger than bootstrap capacitor CBS is recommended.
5) Input signal is High-Active type. There is a 5k
W 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. RSCPS time constant should be selected in the range 50~150ns. (Recommended RS=100 , CPS=1nF)
6) To prevent errors of the protection function, the wiring around RF and CSC should be as short as possible.
7) In the short-circuit protection circuit, please select the RFCSC time constant in the range 1.5~2ms.
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
capacitor of around 0.1~0.22
mF between the P&GND pins is recommended.
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 CBS. Also, choose 0.1~0.2mF R-category ceramic capacitors with good temperature and
frequency characteristics in CBSC.
13) For the detailed information, please refer to the AN-9070 and FEB306-001.
