bipolar latching or unipolar digital hall
This device is a bipolar hall effect sensor, meaning it acts like a bistatic latching switch. The magnetic polarity has to be reversed to change the state of the switch. A unipolar device should only turn on in the presence of a magnetic field and then turn off when the field is gone.

latch mode (note that the B HYS band incorporates B = 0), panel B shows unipolar switch behavior (the B HYS band is more positive than B = 0), and panel C shows negative switch behavior (the B HYS band is more negative than B = 0). Bipolar devices, such as the A1250, can operate in any of the three modes.

Take normal ESD precautions in handling this product to prevent ESD-induced damage and/or degradation Latch vs Unipolar vs Bipolar Hall Effect Sensors AVR Nov 15, 2009 · I was playing around with a latch hall effect sensor and found that when one magnetic field was put by it, it would turn on, and reversing the field would turn it off. My question is, how to unipolar or bipolar sensors work? Would unipolar mean that field applied = on, field removed = off ? What about bipolar?
