coupling at each SPM input is recommended in order to prevent input signals’ oscillation and it should be as close as possible to each
SPM input pin.
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
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 Fig. 12.
4) C
SP15
of around 7 times larger than bootstrap capacitor C
is recommended.

output pulse width should be determined by connecting an external capacitor(C
FOD
) between C
FOD
(pin8) and COM
(L)
(pin2). (Example : if C
FOD
= 33 nF, then
t
= 1.8 ms (typ.)) Please refer to the note 6 for calculation method.
6) Each input signal line should be pulled up to the 5V power supply with approximately 4.7k
(at high side input) or 2k
(
at low side input) resistance (other RC
coupling circuits at each input may be needed depending on the PWM control scheme used and on the wiring impedance of the system’s printed circuit board).
Approximately a 0.22~2nF by-pass capacitor should be used across each power supply connection terminals.
7) To prevent errors of the protection function, the wiring around R
, R
and C
should be as short as possible.
8) In the short-circuit protection circuit, please select the R
C
time constant in the range 3~4
μ
s.
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&N pins should be as short as possible. The use of a high frequency non-
inductive capacitor of around 0.1~0.22
μ
F between the P&N 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. It is recommended that the distance be 5cm at least.
