XC3202 Series
Low Power Consumption Hall IC (Magnetic Sensor)
ETR0412-005
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).
APPLICATIONS
Cover detector, Home security systems Mobile phones Electronic dictionaries Portable game consoles Home electronics (refrigerators, washing machines etc)

*1: When the magnetic flux density to the IC becomes larger than Bop, the IC goes into an on-state and outputs a low signal (VOUT=Low) at the leading edge of the next "tawake" pulse. *2: When the magnetic flux density to the IC becomes lower than Brp, the IC goes into an off-state and outputs a high signal (VOUT=High) at the leading edge of the next "tawake" pulse. During the other periods, the previous state is maintained.
