OBSOLETE – PART DISCONTINUED PART OBSOLETE – NO ALTERNATE PART AH1886 MICROPOWER, ULTRA-SENSITIVE HALL EFFECT SWITCH Description Pin Assignments AH1886 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 15µWin 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.
