General Description

Hall

Plate

The SS239 Omnipolar Hall effect sensor IC is fabri-

cated from mixed signal CMOS technology. It incor-

porates advanced chopper-stabilization techniques to

provide accurate and stable magnetic switch points.

GND

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 B_OP/B_RPthresholds

then the output transistor is driven to change states accordingly. While in the “Sleep” cycle the output transistor 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 SS239 will be latched on (B_OP) 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 (B_RP) in the absence of a

magnetic field.
