摘要：An integrated circuit preferably to be connected to a motor vehicle battery isselectively switchable between sleep and normal operating modes. The IC may include a
useful control logic circuit, a wake-up circuit evaluating an input signal and responsivelyoutputting a wake-up signal dependent on the input signal, and an input control andsupply circuit connected between the wake-up circuit and the control logic circuit. Thewake-up circuit includes at least one recognition circuit having an amplifier arrangementto selectively amplify the input signal, and an evaluation circuit having a switch
arrangement controlled by the amplified signal and an amplifier producing the outputsignal. The wake-up circuit has a very low current consumption while monitoring the inputsignal, and produces the wake-up signal only if the input signal suitably exceeds or fallsbelow a specified voltage threshold. The wake-up signal may activate the control circuit,which may activate the logic circuit.
