Overview
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 fabricated from mixed signal CMOS technology .
It incorporates 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 capacitor techniques to eliminate the amplifier offset voltage, which, in bipolar devices, is a major source of temperature sensitive drift.
CMOS makes this advanced technique possible.
The CMOS chip is also much smaller than a bipolar chip, allowing very sophisticated circuitry to be placed in less space.
The small chip size also contributes to lower physical stress and less power consumption.
