As an example the choice of C18 = 22nF and C13 = 47nF yields
T
T
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
chosen to be shorter than T
It has to be noted finally that during the turn-on duration T
consumption is increased by the 220µA needed to charge C13.
The precharge circuit may be disabled if C18 is not equipped. This yields a T
zero. Note that the sum of R
THRES pin as this voltage is internally used also as the reference for the FSK
demodulator.
