AH1883
MICROPOWER, ULTRA-SENSITIVE HALL EFFECT
SWITCH
Description
Pin Assignments
AH1883 is with two Hall effect plates and a CMOS output
driver, mainly designed for battery–powered, hand-held
equipment (such as Cellular and Cordless Phone, PDA).
The total operation power is down to 15uW in the 1.8V
supply.

Output
Vdd
Either north or south pole of sufficient strength will turn the
output on. The output will be turned off under no magnetic
field.
SOT553
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.
