HK451 - High sensitivity omnipolar Hall sensor
HK451 High sensitivity omnipolar Hall sensor 1.Introduction HK451 is an omnipolar Hall-effect switch designed and produced based on a bipolar semiconductor (Bipolar) process and is sensitive to the south and north poles.
The device integrates a voltage generator that can work stably under a power supply voltage of 3.5 to 60V, temperature compensation circuit, small signal amplifier, Schmitt trigger and open collector output.
The sensor can work in the South and North Pole.
