Abstract
A power element and a temperature sensing element are formed on the same semiconductor substrate, and one end of a PN junction of the temperature sensing element is connected to a ground potential (VSS) or a power supply potential (VDD) through an intermediation of a resistor. A sum of a potential difference between both ends of the PN junction and a potential difference between both ends of the resistor is used as a temperature detection signal. The temperature sensing element can thus be formed in a recess formed in the power element while avoiding latch-up.
