1. An integrated circuit arrangement comprising:

  • connection terminals configured to receive a supply voltage,an undervoltage detector coupled between the connection terminals and configured to compare the supply voltage with a select reference value selected from a first reference value and a second reference value, the second reference value less than the first reference value, and to produce a detector signal on the basis of a result of the comparison,at least one circuit unit coupled between the connection terminals, the at least one circuit unit including at least one first operating state with a first drawn current and a second operating state with a second drawn current, the second drawn current exceeding the first drawn current,wherein the select reference value corresponds to the first reference value during the first operating state, and corresponds to the second reference value during the second reference state.
