Current consumption monitoring device for checking an electronic circuit's consumption comprises a capacitor arranged in parallel to the circuit to be monitored together with a switch for isolating the so created parallel circuit

摘要

Device (10) for monitoring the current consumption (Iq) between first and second potentials of a switched circuit (12) comprises the following: a capacitor (18) in parallel to the circuit arrangement that is to be monitored; a switch (16) for isolation of the parallel circuit of the monitored circuit and capacitor for the first or second potential; and an arrangement (20) for monitoring the potential of the side of the circuit separated from the first or second potential. An Independent claim is made for a method or monitoring the current consumption between first and second potentials of a switched circuit.
