An electronic circuit device comprises an output part, which includes at least three phase parts and a first temperature sensor and a second temperature sensor, which output detection signals corresponding to temperatures of the output part. Each phase part includes two high-side and low-side switching elements. The first temperature sensor is located at a position between the first phase part and the second phase part. The second temperature sensor is located at a position between the second phase part and the third phase part. The electronic circuit device further comprises a control circuit part, which specifies a phase part of overheat among the phase parts based on the detection signals of the first temperature sensor and the second temperature sensor.

Electronic circuit device

A pressure sensor includes a case having a concave portion, a sensing portion disposed in the concave portion to output an electrical signal proportional to an applied pressure, a circuit portion disposed in the concave portion and connected to the sensing portion and a conductive diaphragm fixed to the case to cover the concave portion. A conductive member surrounds the sensing portion and the circuit portion to provide an electrical shield. The diaphragm is used as a part of the conductive member.
