TDA 5210
Wireless Components
Specification, May 2001
e-Fkt2.WMF
Figure 4-12
Voltage transient on capacitor C attached to pin 20
As an example the choice of C2 = 22nF and C = 47nF yields
τ
2
= 0.44ms
T
2
= 0.71ms
T
3
= 0.53ms
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 220μA needed to charge C.
The precharge circuit may be disabled if C2 is not equipped. This yields a T2
close to zero. Note that the sum of R4 and R5 has to be 600k
in order to pro-
duce 3V at the THRES pin as this voltage is internally used also as the refer-
ence for the FSK demodulator.
