Description
AH1887 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
output on. The output will be turned off under no magnetic
field.
While the magnetic flux density (B) is larger than operate
point Bop(s), the output1 will be turned on (low), the output is
held until B is lower than release point Brp(s), then turned off
(high).
While the magnetic flux density (B) is larger than operate
point Bop(n), the output2 will be turned on (low), the output is
held until B is lower than release point Brp(n), then turned off
(high).
