OH44 Unipolar Hall Effect Switch IC
General Description:
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 position control, speed detection, flow detection occasions as a non-contact switch.
