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 possibility 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 parasitic diode is ±20mA. 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 condition, an external clamping diode (Dx) is needed to protect the IC
from rush current.
