Abstract
A circuit arrangement () for detecting undervoltage in an energy source () includes a transistor switch () and at least one further switch element (). The transistor switch () and the further switch element () are of low impedance in an operating state of the circuit arrangement (). The transistor switch () blocks the further switch element () for interrupting the voltage supply if a supply voltage (U) of the energy source () is below a defined voltage value (U).
