1 Functional Diagram

2 General Description

The MLX90248 Omnipolar

IC is fabricated from mixxed signal CMOS

technology. It incorporates advanced chopper-

Hall effect sensor

stabilization techniques to provide accurate and

stable magnetic switch points.

The circuit design provides ann 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 intoo a “Sleep” mode.

Periodically the device is ““Awakened” by this

internal logic and the magnettic flux from the Hall

element is evaluated againnst 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 transsistor is latched in its

previous state. The design h

equiring extended

The output transistor of the 990248 will be latched

on (BOP) in the presence of a sufficiently strong

South or North magnetic fieldd facing the marked

side of the package. The outpput will be latched off

(BRP) in the absence of a maggnetic field.
