Wireless Components
Specification, May 2003
This circuit charges the capacitor C with an inrush current I
load
of 240μA for a
duration of T
2
until the voltage U
c
appearing on the capacitor is equal to the volt-
age U
s
at the input of the data filter. This voltage is limited to 2.5V. As soon as
these voltages are equal or the duration T
2
is exceeded the precharge circuit is
disabled.
2
is the time constant of the charging process of C which can be calculated as
2
20k · C2
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:

Voltage appearing on C2 during precharging process
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
