SS5681
Unipolar Hall Switch-Low Sensitivity
General Descriptions
The SS5681 is a unipolar Hall-effect sensor IC fabricated from CMOS technology.
The device integrates a voltage regulator, Hall sensor with dynamic offset cancellation system, small signal amplifier, Schmitt trigger and an open-drain output driver.
With suitable output pull up, they can be used with bipolar or CMOS logic circuits.
These Hall-effect switches are monolithic integrated circuits with tighter magnetic specifications, designed to operate continuously over extended temperatures to +150℃,and are more stable with both temperature and supply voltage changes.
The unipolar switching characteristic makes these devices ideal for use with a simple bar or rod magnet.
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.
