Abstract
The invention relates to a two-chip power IC, in which a sensor chip having a sensor is mounted on a switch chip having a switch. The sensor is electrically connected to the switch in order to turn the switch off when a temperature detected by the sensor exceeds a threshold value which can be preset. In order to ensure that the sensor chip is heated more quickly, at least one supply line for the switch is routed in the vicinity of the sensor so as to assure good heat transfer from the supply line to the sensor.
