Abstract
A circuit for processing a wake-up signal, which is usable for activating electrical devices. The circuit includes an evaluation circuit, which checks an applied wake-up signal for its validity, and an output driver circuit, which outputs a processed wake-up signal when the evaluation circuit evaluates the applied wake-up signal as valid. The evaluation circuit has a comparator, which compares the applied wake-up signal to at least one threshold value for the evaluation. The evaluation circuit includes an input circuit and a switchable constant voltage source via which at least one criterion for evaluating the applied wake-up signal is adjustable in each case. The comparator is a multi-channel, integrated comparator circuit, and the individual channels of the integrated comparator circuit evaluating one criterion of an applied wake-up signal in each case.
