OPERATION

The output of these devices (pin 3) switches low when the magnetic field

at the Hall sensor exceeds the operate point threshold (BOP). At this point, the

output voltage is VOUT(SAT). When the magnetic field is reduced to below the

release point threshold (BRP), the device output goes high. The difference in

the magnetic operate and release points is called the hysteresis (Bhys) of the

device. This built-in hysteresis allows clean switching of the output even in

the presence of external mechanical vibration and electrical noise.

Extensive applications information for Hall-effect sensors is available in:

• Hall-Effect IC Applications Guide, Application Note 27701;

• Hall-Effect Devices: Soldering, Gluing, Potting, Encapsulating, and Lead

Forming, Application Note 27703.1;

• Soldering of Through-Hole Hall-Sensor Dervices, Application Note 27703;

and

• Soldering of Surface-Mount Hall-Sensor Devices, Application Note 27703.2.
