Abstract
An integrated circuit arrangement includes connection terminals, an undervoltage detector, and at least one circuit unit. The connection terminals are configured to receive a supply voltage. The undervoltage detector is coupled between the connection terminals and is 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 is less than the first reference value. The undervoltage detector is further operable to produce a detector signal on the basis of a result of the comparison. The circuit unit is coupled between the connection terminals, and includes a first operating state with a first drawn current and a second operating state with a second drawn current. The second drawn current exceeds the first drawn current. The select reference value corresponds to an operating state of the at least one circuit unit.
