MLX90248 (New Generation) Datasheet
The MLX90248 OmnipolarTM 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 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.
This datasheet provides all technical details of the MLX90248.
