General Description:

The SS249 Omnipolar Hall effect sensor IC is fabricated from mixed signal CMOS technology .It incorporates

advanced chopper-stabilization techniques to provide accurate and stable magnetic switch points.

The output transistor of the SS249 will be latched on (BOP) in the presence of a sufficiently strong South or North

magnetic field facing the marked side of the package. The output will be latched off (BRP) in the absence of a

magnetic field.
