MOBILE DATA CARRIER

摘要

Disclosed is a mobile data carrier comprising a data-processing circuit; and a supply unit ( 1 ) to apply electric energy to power supply terminals for operating the data-processing circuit from an external energy source and ( 2 ) controlling voltage and current at external access points of the data carrier, wherein the supply unit including a voltage-limiting control circuit arranged in parallel to the power supply terminals of the data-processing circuit, and a current control device which, with respect to the supply of energy to the data-processing circuit, is arranged in series with the parallel arrangement of the voltage-limiting control circuit and the data-processing circuit.
