Zusammenfassung:A voltage generator arrangement which comprises a voltage converter (40) and a polarity detection circuit (10). The voltage converter (40) is coupled to a supply voltage terminal (9) and an output terminal (7) and comprises a first mode of operation (P1) for a positive supply voltage (VIN) and a second mode of operation (P2) for a negative supply voltage (VIN). The polarity detection circuit (10) is coupled to the supply voltage terminal (9) and a control input terminal (47) of the voltage converter (40), for providing a first pilot signal (SP1) depending on the polarity of the supply voltage (VIN).
