AH451 High sensitivity omnipolar Hall sensor Introduction Vinbelltech Limited AH451 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 3.8 to 40V, reverse voltage protection circuit, temperature compensation circuit, small signal amplifier, Schmitt trigger and open collector output. The sensor can work in the South and North Pole. When the magnetic flux density (B) is greater than the operating point Bop, the output will be turned on at a low output level. Then keep the output until the magnetic flux (B) is lower than the release point Brp.
