FCAS50SN60 Rev. A
F
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 Module, 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 4.7k
resistance. Please refer to Figure
10
.
4. C
SP15
of around 7 times larger than bootstrap capacitor C
BS
is recommended.
5. V
output pulse width should be determined by connecting an external capacitor(C
FOD
) between C
FOD
(pin7) and COM(pin2). (Example : if C
FOD
= 33 nF, then t
FO
=
1.8
ms
(typ.)) Please refer to the note 6 for calculation method.
6. Input signal is High-Active type. There is a 3.3k
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
SC
, 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 3~4
μ
s.
9. Each capacitor should be mounted as close to the pins 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 capac-
itor of around 0.1~0.22
μ
F between P and 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.
12. C
SPC15
should be over 1uF and mounted as close to the pins of the module as possible.
13. N
B1
(pin23) and N
B2
(pin21) should be shorted externally.
