摘要:
Disclosed is a circuit arrangement (10) for recognizing an undervoltage of an energy source (12). Said circuit arrangement (10) comprises a transistor switch (48) and at least one additional switching means (30). The inventive circuit arrangement (10) is characterized in that the transistor switch (48) and the additional switching means (30) have a low resistance in an operational state of the circuit arrangement (10) while the transistor switch (48) blocks the additional switching means (30) in order to interrupt the voltage supply when a supply voltage (U) of the energy source (12) drops below a defined voltage value (US).
