Functional Description

Power Supply, Pin 8

To achieve interference protection and surge immunity, the supply voltage pin 8 must be provided with an RC circuit as shown in Figure The dropping resistor, R1, limits the current in case of overvoltage, whereas C1 smooths the supply voltage at pin

Recommended values are R1 = 510Ω, C1 = 47µF. An integrated Z-diode 14V protects the supply voltage, VS, thus enabling stable operation in a supply-voltage range of 6V to 16V, supplied by VBatt. It is possible to operate the integrated circuit with a 5V 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 2-2 on page 4, and the R1C1 circuit is omitted.
