Ordering Information:

Overview : OH443 high-temperature Hall unipolar switch circuit by the regulator, Hall- film, differential amplifier, Schmitt trigger and output stage under the influence of an external magnetic field, when the magnetic flux density exceeds the turn-on threshold BOP, Hall. after the circuit output MOSFET, output low ., B to add, remains an on-state. If the value of the applied magnetic field B is reduced to BRP, the output MOSFET is off, the output high .
