AH1887-ZG-7 is with two Hall effect plates and dual CMOS outputdriver, mainly designed for battery–powered, hand-heldequipment (such as Cellular and Cordless Phone, PDA). Thetotal operation power is down to 15uW in the 1.8V supply. Eithernorth 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 pointBop(s), the output1 will be turned on (low), the output is held untilB is lower than release point Brp(s), then turned off(high).While the magnetic flux density (B) is larger than operate pointBop(n), the output2 will be turned on (low), the output is held untilB is lower than release point Brp(n), then turned off(high).
Feature
