SS4913

CMOS Omnipolar High Sensitivity Micropower Hall Switch

Features



Micropower consumption for battery powered applications

Omnipolar, output switches with absolute value of North or South pole from magnet

Operation down to 2.5V

High sensitivity for direct reed switch replacement applications

3 pin SOT23 (suffix SO)

General Description:

The SS4913 Omnipolar 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.

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 SS4913 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.

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

Applications



Solid state switch

Handheld Wireless Handset Awake Switch

Lid close sensor for battery powered devices

Magnet proximity sensor for reed switch replacement in low duty cycle applications
