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 DFN2...
