A semiconductor chip includes at least one power semiconductor switch configured to activate and deactivate current conduction from a first supply terminal, which is connected to a first supply line that provides an unstabilized first supply voltage, to the at least one output terminal in accordance with a respective control signal. In operation, the unstabilized first supply voltage is monitored and an under-voltage is signaled when the unstabilized first supply voltage falls below a first threshold value. The first supply terminal is short circuited with a third terminal when the an under-voltage is signaled.
