SS249

SS249 CMOS Omnipolar High Sensitivity Micropower Hall Switch Packages – Features and Benefits Solid-State Reliability much better than reed Switch – – – Omnipolar, output switches with absolute value of North or South pole from magnet Operation from 3.5V to 24V High sensitivity for direct reed switch replacement applications 3 pin SOT23 (suffix SO) 3 pin SIP (suffix UA)     Functional Block Diagram Application Examples – – – www.DataSheet.net/ Solid state switch Speed detection Interrupter Magnet proximity sensor for reed switch replacement –     General Description: The SS249 Omnipolar Hall effect sensor IC is fabricated from mixed signal CMOS technology .It incorporates advanced chopper-stabilization techniques to provide accurate and stable magnetic switch points. The output transistor of the SS249 will be latched on (BOP) in the presence of a sufficiently strong South or North magnetic field facing the marked side of the package. The output will be latched off (BRP) in the absence of a magnetic field.   1 V2.10 May 1, 2012 Datasheet pdf - http://www.DataSheet4U.co.kr/ SS249 CMOS Omnipolar High Sensitivity Micropower Hall Switch Typical Application Circuit Typical Three-Wire Application Circuit Automotive and Severe Protection Circuit R1:100 C1 VDD R2 OUT C2 GND GND D1 Z1 C1 VDD R2 OUT C2 Environment SS249 SS249 SEC's pole-independent sensing technique allows for operation with either a north pole or south pole magnet orientation, enhancing the manufac...
