Appendix B:
B.1
In order to satisfy the Complete Specification AS-interface an application circuit has to achieve a certain input
impedance. Besides the A²SI-L IC properties the applied external coil will have an significant influence.
Therefore a suitable coil shall be recommended. During the product development period recommended data
of this coil have to be worked out. The following coil is considered as target component and shall be applied
(between ASIP and VIN, refer to Figure 5-1 and Figure 5-2, respectively) as long no other recommendation
has been made:
Coil No, SD75-183k
Core No, M5D DR7.8*5.0 DIM
Maker EASY MAGNET Corp. http://www.easymagnet.com.tw
Inductance: 18mH +-10% (f=1kHz Ambient Temperature : 20'C DC Bias 0A)
DC resistance : Max 72.0 ohm ( Ambient Temperature :20'C DC Bias 0A)

Figure B-1 shows the model parameters that will be used in order to recommend suitable external coils. Until
the end of the development process the following parameters have shall be recommended by ZMDI:
L' : Real value of Inductance
C' : Parasitic capacitor
R' : AC Resistance
Rdc : DC Resistance
Measurement frequency : 50k...300kHz C' R' L'
