XC3202 Series ETR0412-005 Low Power Consumption Hall IC (Magnetic Sensor) ■GENERAL DESCRIPTION The XC3202 series is a Hall effect magnetic sensor IC with a built-in CMOS output driver. The device features low power consumption and small packaging which is ideally suited for battery powered portable applications such as mobile phones, electronic dictionaries and handheld game consoles. When the magnetic flux density (Omnipolar) is larger than the operating magnetic flux density (Bop), the CMOS output driver will be turned on (Detect Low). The output driver will be turned off (Release High) when the output is lower than the release magnetic flux density (Brp). ■FEATURES ■APPLICATIONS Release Magnetic Flux Density : 2.4~5.5V : 8μA : South Pole North Pole : South Pole 3mT(TYP.) -3mT(TYP.) 2mT(TYP.)
