Circuit configuration with temperature protection and method for implementing the temperature protection

摘要

A configuration for protecting an integrated circuit against over-temperature conditions is described. The configuration has at least one detector device, which identifies a disturbance situation of the integrated circuit, at least one temperature sensor, which detects the temperature of at least one part of the integrated circuit, and a logic device. The logic device ascertains a disturbance mode in dependence a detected disturbance situation and/or the detected temperature and which allocates a first temperature switching stage to the temperature sensor in the normal mode and allocates a second, lower temperature switching stage to the temperature sensor in the disturbance mode. Furthermore, the invention relates to an integrated circuit having such a configuration and also to a method for protecting an integrated circuit against over-temperature conditions.
