AH1887数据手册传感器变送器的磁性传感器-开关（固态）规格书PDF

描述 Description

AH1887 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 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).
