Figure 11 shows the input circuit of U6047B. It has an
integrated pull-up resistance (100 k ), RF capacitor
(15 PF) and Z-diode (7 V). The circuit reacts to voltages
less than 2 V. The external protective resistance has a
value of 2 k and the push-button switch is connected to
GND. Contact current, I, is calculated as follows:
V
S
(100 k
2 k )
I
when V
Batt
12 V
I
0.1 mA
It can be increased by connecting a 5.6 k resistor from
the push-button-switch to V
Batt
as shown in figure 19.
The connecting diodes prevent the current flow to the
input of the Z-diodes when the rocker actuated-switch is
in
open-state
(current-consumption
standby-mode). If necessary, these diodes can be omitted.
