NOT RECOMMENDED FOR NEW DESIGN AH1803 USE AH1806 Green MICROPOWER, ULTRA-SENSITIVE HALL EFFECT SWITCH Description Pin Assignments (Note 4) The AH1803 has two Hall effect plates and a CMOS output driver. SC59 (commonly known as SOT23 in Asia) The device is primarily designed for battery-operated, handheld ( Top View ) equipment (such as cellular and cordless phones, PDAs). The total operation power is down to 24W in the 3V supply. 2. Output Either the north or south pole turns the output on with sufficient strength. The output turns off under no magnetic field. GND 3. 1. Vdd 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).
