POINTE CLAIRE, Quebec, Canada — Future Electronics, a global leading distributor of electronic components, promotes Diodes inc.'s AH1902 Series of high sensitivity micropower omnipolar Hall effect switches.
The AH1902 is a low voltage high performance micropower omnipolar Hall effect switch designed and optimized to operate over the supply range of 1.6V to 3.6V and consumes an average current of 4.3uA typical at 1.8V.
The single output is activated with either a north or south pole of sufficient magnetic field strength. When the magnetic flux density (B) perpendicular to the package is larger than operate point (Bop), the output will be turned on (pulled low) and held until B is lower than release point (Brp). The output will remain off when there is no magnetic field.
