MAGNETIC SENSOR APPARATUS AND CURRENT SENSOR APPARATUS
First Claim
1. A magnetic sensor apparatus comprising:
- a magnetic sensor element;
an amplifying section that amplifies and outputs an output of the magnetic sensor element;
a plurality of comparing sections that compare the output of the magnetic sensor element or an output of the amplifying section to a threshold value; and
a plurality of delaying sections that each delay and output a comparison result output by a corresponding comparing section among the plurality of comparing sections.

Abstract
A sensor apparatus adjusts output timings of a detection signal and a sensing signal for sensing an abnormality in the detection signal. Provided is a magnetic sensor apparatus comprising a magnetic sensor element, an amplifying section that amplifies and outputs an output of the magnetic sensor element, a plurality of comparing sections that compare the output of the magnetic sensor element or an output of the amplifying section to a threshold value, and a plurality of delaying sections that each delay and output a comparison result output by a corresponding comparing section among the plurality of comparing sections. Also provided is a current sensor apparatus including a current path through which a current serving as a measurement target flows and a magnetic sensor apparatus that is arranged corresponding to the current path and detects a magnetic field generated according to the current serving as the measurement target.
