NOTE1) Each specification is defined by testing above items individually.
NOTE2) When shifting the sensor output from H to L, please make sure the magnetic field
applied to the sensor becomes higher than the above operating magnetic field (Hon)
through your designing.
NOTE3) When shifting the sensor output from L to H, please make sure the magnetic field
applied to the sensor becomes lower than the above operating magnetic field (Hoff)
through your designing.
NOTE4) Sensitivity selection of this product is performed at Vcc=3.0V. Operating magnetic field
can possibly change when applying the supply voltage other than 3.0V. Please consult
with us for technical assistance when you consider the supply voltage other than 3.0V, as
a special attention needs to be given in the design.
