1. Functional Diagram

2. General Description

The MLX90248 Omnipolar

Hall effect sensor 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

thresholds 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 90248 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.
