Block Diagrams
Note A: Cx, Rx, Dx are external Capacitor, Resistor, and
Diode, respectively.
Note B: External clamping diode, Dx;
External capacitor is charged to VCC level in the wait
state, i.e. when no trigger is applied.
If the supply voltage is turned off, Cx discharges mainly
through the internal (parasitic) diode. If Cx is sufficiently
large and VCC drops rapidly, there will be some possibil-
ity of damaging the IC through in rush current or latch-
up. If the capacitance of the supply voltage filter is large
enough and VCC drops slowly, the in rush current is
automatically limited and damage to the IC is avoided.
The maximum value of forward current through the para-
sitic diode is ±20 mA. In the case of a large Cx, the limit
of fall time of the supply voltage is determined as follows:
tf ≥ (VCC – 0.7) Cx / 20mA
(tf is the time between the supply voltage turn off and the
supply voltage reaching 0.4 VCC)
In the event a system does not satisfy the above condi-
tion, an external clamping diode (Dx) is needed to
protect the IC from rush current.
