OCH181
Micro-power, High Sensitivity, Bipolar Detection Type Hall-IC
General Description
The OCH181 developed using CMOS technology,
is a bipolar detection type Hall IC with a high-sensitivity
that operates on a low current. In the Hall IC, a Hall
element, an offset cancel circuit, an amplifier circuit, a
sample and hold circuit, a Schmidt circuit, and output
stage FET are integrated on a single chip housed in a
small package by IC technique. The output voltage
changes when the OCH181 detects the intensity level
of flux density and a polarity change. Using the
OCH181 with a magnet makes it possible to detect
rotation in various devices.
The OCH181 is available in DFN2020-6L
packages. Operating temperature range of the
OCH181 is from -40°C to 85°C.
