The GH1881 is a magnetic sensor integrated circuit designed using CMOS process technology. It comprises a voltage regulator, a Hall sensor with a dynamic offset compensation system, a small signal amplifier, a Schmitt trigger, and a drain open output driver. This sensor converts magnetic induction intensity into a switch-type digital voltage signal, suitable for operation with rectangular or cylindrical magnets. The output is high in the absence of a magnetic field and switches to low when the magnetic field strength exceeds the operating point (BOP). The output remains low until the magnetic field strength drops below the release point (BRP), at which point it returns to a high state.
