摘要： An object is to provide a magnetic sensor module that suppresses a size of a magnetic sensor chip while applying a uniform calibration magnetic field to a magneto-resistive element. Provided is a magnetic sensor module comprising an IC chip having a first coil; and a magnetic sensor chip that is disposed on a surface of the IC chip and includes a first magnetic sensor that detects magnetism in a direction of first axis, wherein a planar shape of the IC chip encompasses a planar shape of the magnetic sensor chip, and the first coil has a planar shape including three or more sides, and is, when seen in a cross section along at least one side of the planar shape, is formed so as to cover a region, in a direction of the one side, of the first magnetic sensor.

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： Provided is an apparatus including: a first input circuit which inputs signal from a first communication line; a second input circuit which inputs a signal from a second communication line; a reference voltage generation circuit which generates a reference voltage; and a comparison circuit which compares the reference voltage with a voltage of the first communication line. The first input circuit and the second input circuit adjust judgement thresholds to be used for judging a signal value according to the comparison result obtained by the comparison circuit.
