OH37 Unipolar Hall Effect Switch IC
General Description:
Part No. OH37
Operate temperature: -40～85℃
Package:3000pcs/reel
OH37 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. OH37, with the feature
of small size (SOT23 package) and stable performance in -40～85℃, have been widely used in
various fields as a non-contact switch IC.
