    摘要： An object is to provide a magnetic sensor module reducing influence of heat generated from a coil on a magnetic sensor. A conventional method requires, on a magnetic sensor chip, multiple temperature measuring circuits corresponding to multiple magnetic sensors, and many pads for connection to an IC chip. Therefore, the problem is increase in size of the sensor chip mounting the sensors and in manufacturing cost. Provided is a magnetic sensor module comprising an IC chip including a first coil, a first pad connected to one end of the coil, and a second pad to the other end; a magnetic sensor chip disposed on the IC chip's surface, including a first magnetic sensor detecting first axial magnetism; a first external output terminal; a first conductive wire for connecting the first pad and terminal; a second external output terminal; and a second conductive wire for connecting the second pad and terminal.

    摘要： A resonance inverter includes a first coil provided between an input terminal and a switch element, a first capacitor provided between the drain and the source of the switch element, a second capacitor serially connected between the drain and the source of the switch element, and a second coil. A drain-source voltage of a switch element can be effectively lowered, by setting a serial resonance frequency based on the second coil and the second capacitor to a value higher than twice of a driving frequency, and lower than 2.75 times thereof.
