OCH186
Unipolar Detection Type Hall-IC
General Description
The OCH186 using CMOS technology is a
unipolar detection type Hall IC. 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.
South poles of sufficient strength will turn the
output on. The output will be turned off under no
magnetic field. While the magnetic flux density (B) is
larger than operating point (BOP), the output will be
turned on (low), the output is held until B is lower than
release point (BRP), and then turned off.
The OCH186 is available in TSOT23-3L
Package. Operating temperature range of the
OCH186 is from -40°C to 85°C.
To minimize the BOM cost, capacitors of the
MLCC type are supported, and only one external
component is needed to complete the application
circuit.
