U
Smax
= 2.5V which is also the approximate operating point of the data filter
input. The time constant appearing in this case can be denoted as T3, which
can be calculated with
e-Fkt2.WMF
Figure 4-12
Voltage transient on capacitor C attached to pin 20
As an example the choice of C2 = 20nF and C = 47nF yields
2
= 0.4ms
T
2
= 0.64ms
T
3
= 0.49ms
This means that in this case the inrush current could flow for a duration of
0.64ms but stops already after 0.49ms when the U
Smax
limit has been reached.
T3 should always be chosen to be shorter than T2.
It has to be noted finally that during the turn-on duration T2 the overall device
power consumption is increased by the 240μA needed to charge C.
