Wireless Components
This circuit charges the capacitor C with an inrush current I
220µA for a duration of T
equal to the voltage U
2.5V. As soon as these voltages are equal or the duration T
precharge circuit is disabled.
as the sum of R1 and R2 is sufficiently large and thus can be neglected. T2 can
then be calculated according to the following formula:
The voltage transient during the charging of C2 is shown in the following figure:
Figure 4-11
The voltage appearing on the capacitor C connected to pin 20 is shown in the
following figure. It can be seen that due to the fact that it is charged by a con-
stant current source it exhibits is a linear increase in voltage which is limited to
U
input. The time constant appearing in this case can be denoted as T3, which
can be calculated with
