Parasitic capacitance of the external

over-voltage protection diode (Zener

diode)

CZener

The equivalent circuit of a slave, which is calculated from the impedance of the SAP5 and the parallel external over-voltage

protection diode (Zener diode), must satisfy the requirements of the AS-Interface Complete Specification for Extended Address

Mode slaves.

After the maximum parasitic capacitance of the external over-voltage protection diode (20pF) has been subtracted, the specifications

group including RIN1, LIN1 and CIN1 or the specifications group including RIN2, LIN2 and CIN2 must be met for compliance with the

AS-Interface Complete Specification V3.0.

Note: A decoupling capacitor defines the internal low-pass filter time constant; lower values decrease the impedance but improve the

turn-on time. Higher values do not improve the impedance but do increase the turn-on time. The turn-on time also depends on the load

capacitor at UOUT. After connecting the slave to the power, the capacitor is charged with the maximum current IUOUT. The impedance will

increase when the voltage allows the analog circuitry to fully operate.
