An electronic circuit device (100) comprises an output part (20), which includes at least three phase parts (20a to 20c) and a first temperature sensor (31) and a second temperature sensor (32), which output detection signals corresponding to temperatures of the output part (20). Each phase part (20a to 20c) includes two high-side and low-side switching elements (201-206). The first temperature sensor (31) is located at a position between the first phase part (20a) and the second phase part (20b). The second temperature sensor (32) is located at a position between the second phase part (20b) and the third phase part (20c). The electronic circuit device (100) further comprises a control circuit part (40), which specifies a phase part of overheat among the phase parts (20a to 20c) based on the detection signals of the first temperature sensor (31) and the second temperature sensor (32). 种电子电路装置(100)包括输出部分(20)，输出部分(20)包括至少三个相部分(20a至20c)以及第温度传感器(31)和第二温度传感器(32)，第温度传感器(31)和第二温度传感器(32)输出与输出部分(20)的温度相对应的检测信号。每个相部分(2
