AH1803
MICROPOWER, ULTRA-SENSITIVE HALL EFFECT
SWITCH
General Description
Features
AH1803 is with two Hall effect plates and a CMOS output driver,
mainly designed for battery–operation, hand-held equipment
(such as Cellular and Cordless Phone, PDA). The total operation
power is down to 24uW in the 3V supply.
Either north or south pole of sufficient strength will turn the output
on. The output will be turned off under no magnetic field.
While the magnetic flux density (B) is larger than operate point
(Bop), the output will be turned on (low), the output is held until B
is lower than release point (Brp), then turned off (High).
