Green
MICROPOWER, ULTRA-SENSITIVE HALL EFFECT SWITCH
Description
The AH1803 has two Hall effect plates and a CMOS output driver. The device is primarily designed for battery-operated, handheld equipment (such as cellular and cordless phones, PDAs). The total operation power is down to 24µW in the 3V supply.
Either the north or south pole turns the output on with sufficient strength. The output turns off under no magnetic field.
While the magnetic flux density (B) is larger than operate point (Bop), the output turns on (low). The output is held until B is lower than release point (Brp) then turns off (high).
