HX6278 Specifications Low Sensitivity Unipolar Hall Effect Switch HX6278 is an unipolar Hall effect sensor IC. It incorporates advanced chopper stabilization technology to provide accurate and stable magnetic switch points. The design, specifications and performance have been optimized for applications of solid state switches. The output transistor will be switched on (BOP) in the presence of a sufficiently strong South pole magnetic field facing the marked side of the package. Similarly, the output will be switched off (BRP) in the presence of a weaker South field and remain off with 0 field. The package type is in a Halogen Free version was verified by third party organization. Halogen Free package is available by customers option. Features and Benefits CMOS Hall IC Technology Solid-State Reliability Chopper stabilized amplifier stage Unipolar, output switches with absolute value of South pole from magnet Operation down to 3.0V High Sensitivity for direct reed switch replacement applications 100% tested at 125 for K Spec. Custom sensitivity / Temperature selection are available. Applications Solid state switch Limit switch Current limit Interrupter Current sensing Magnet proximity sensor for reed switch replacement 1 / 5 HX6278 Specifications Low Sensitivity Unipolar Hall Effect Switch Functional Diagram VDD Out Voltage Regulator Amp Hall Sensor GND .
