SS275
CMOS Omnipolar High Sensitivity Micropower Hall Switch
Features
− Solid-State Reliability much better than reed
switch
− Omnipolar, output switches with absolute value
of North or South pole from magnet
− Wide operating voltage range from 3.5V to 24V
− High sensitivity for direct reed switch replace-
ment applications
Applications
− Solid state switch
− Speed detection
− Interrupter
− Magnet proximity sensor for reed switch re-
placement
3 pin SOT23 (suffix SO)
General Description
The SS275 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 output transistor of the SS275 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.
3 pin SIP (suffix UA)
The chopper stabilized amplifier uses switched capac-
itor techniques to eliminate the amplifier offset volt-
age, which, in bipolar devices, is a major source of
temperature sensitive drift. CMOS makes this ad-
vanced technique possible. The CMOS chip is also
much smaller than a bipolar chip, allowing very so-
phisticated circuitry to be placed in less space. The
small chip size also contributes to lower physical
stress and less power consumption.
