OH44 Unipolar
Hall Effect Switch IC
General DeSCRJPTion:
Part No.: OH44
Operate temperature: -40～125℃
Package: 1000pcs/bag
OH44 Hall switch IC is internally consisted by reverse
voltage protection device, voltage regulator, hall voltage
generator, a differential amplifier, Schmitt trigger and the open
collector output level, which can change magnetic field signal into
digital voltage output. With the typical feature of small size and
stable performance, OH44 is widely used in all kinds of POSTTTION
control, speed detection, flow detection occasions as a non-contact
switch.
