Functional Description
Power Supply, Pin 8
For reasons of interference protection and surge immu-
nity, the supply voltage (Pin 8) must be provided with an
RC-circuit as shown in figure 2. Dropper resistor, R
1
, lim-
its the current in case of overvoltage, whereas C
1
smoothes the supply voltage at Pin 8.
Recommended values are: R
1
= 1 k , C
1
= 47 F.
An integratd Z-diode (7.3 V) generates the stabilized
voltage, V
stab
, therefore, the operation of the IC is
possible between 6 V and 16 V, supplied by V
Batt
(Terminal 15).
