Description 
 
AH1885 is with two Hall effect plates and dual CMOS
output driver, mainly designed for batterypowered, 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
output1 on. The output1 will be turned off under no
magnetic field.
 
While the magnetic flux density (B) is larger than operate
point (Bop), the output1 will be turned on (low), the output1
is held until B is lower than release point (Brp), then turned
off.
