XC3202B Series ETR2602-005a Low Power Consumption Hall IC (Magnetic Sensor) ■GENERAL DESCRIPTION The XC3202B 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 is higher than the operating point (Bop), the Low level signal is output. The High level signal is output when the magnetic flux density is lower than the release point (Brp). ■APPLICATIONS ■FEATURES ●Cover detectors Supply Voltage Range : 2.4~5.5V ●Mobile phones Average Supply Current Operating Point Release point : 8μA : South Pole North Pole : South Pole 3mT(TYP.) -3mT(TYP.) 2mT(TYP.)
