AH1885 is with two Hall effect plates and dual 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.

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.
