General Description
The SS109 is a unipolar Hall effect sensor IC fabricated
from mixed signal CMOS technology. The device
integrates a voltage regulator, Hall sensor with dynamic
offset cancellation system, Schmitt trigger and an
open-drain output driver, all in a single package.
It incorporates advanced chopper stabilization techniques to provide accurate and stable magnetic switch points. There
are many applications for this HED – Hall Electronic Device - in addition to those listed above.
Thanks to its wide operating voltage range and extended choice of temperature range, it is quite suitable for use in
automotive, industrial and consumer applications.
The device is delivered in a Small Outline Transistor (SOT) or in a Plastic Single In Line ( SIP 3L flat). Both 3-lead
packages are RoHS compliant.
