General Description

The SS3212 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 circuit design provides an internally controlled clocking mechanism to cycle power to the Hall element and

analog signal processing circuits. This serves to place the high current-consuming portions of the circuit into a

“Sleep” mode. Periodically the device is “Awakened” by this internal logic and the magnetic flux from the Hall

element is evaluated against the predefined thresholds. If the flux density is above or below the Bop/Brp thresh-

olds then the output transistor is driven to change states accordingly. While in the “Sleep” cycle the output tran-

sistor is latched in its previous state. The design has been optimized for service in applications requiring extended

operating lifetime in battery powered systems.

The output transistor of the SS3212 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.
