AH1884
MICROPOWER, ULTRA-SENSITIVE HALL EFFECT
www.SDaWtaSITheCetH4U.com
Description
Pin Assignments
AH1884 is with two Hall effect plates and dual 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 15uW in the 1.8V 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.
