General Description

The SS248 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.

The circuit design provides an internally controlled

clocking mechanism to cycle power to the Hall ele-

ment 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 thresholds then the

output transistor is driven to change states according-

ly. While in the “Sleep” cycle the output transistor is

latched in its previous state. The design has been op-

timized for service in applications requiring extended

operating lifetime in battery powered systems.

The output transistor of the SS248 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.

Applications
