MAGNETISM SENSOR
Document Type and Number:
WIPO Patent Application WO/2008/029520
Kind Code:
A1
Abstract:
[PROBLEMS] A magnetism sensor of dipole sensing adaptative type capable of
mode change one of one-output or two-output mode especially with a simple circuit
constitution and with one integrated circuit. [MEANS FOR SOLVING PROBLEMS]
The magnetism sensor comprises a mode change section (50) which changes the
mode to a one-output mode in which both a (+) magnetism sensing signal and a (-)
magnetism sensing signal are outputted from a first external output terminal
(40) or a two-output mode in which the (+) magnetism sensing signal is outputted
from the first external output terminal (40) and the (-) magnetism sensing signal
is outputted from a second external output terminal (41). By providing the mode
change section (50) in an integrated circuit (22), mode selection is possible,
and especially such mode change can be realized with a simple circuit constitution
and with one integrated circuit (22), thereby reducing the production cost.
