Functional Description
Power Supply, Pin 8
4771A–AUTO–11/03
To achieve interference protection and surge immunity, the supply voltage (pin 8) must
be provided with an RC circuit as shown in Figure 3. The dropping resistor, R
current in case of overvoltage, whereas C
Recommended values are: R
An integrated Z-diode (14 V) protects the supply voltage, V
ation in a supply-voltage range of 6 V to 16 V, supplied by V
It is possible to operate the integrated circuit with a 5 V supply, but it should be assured
that there are no interference voltages. In this case, pin 7 is connected to pin 8 as shown
in Figure 4 on page 4, and the R
