CXHA3161 is with proprietary Hall effect plate and single CMOS output driver, mainly designed for battery–powered,hand-held equipment (such as Cellular and Cordless
Phone, PDA).When north-pole of sufficient strength on chip or south-pole of sufficient strength under chip, the CXHA3161 will turn on the OUT output. When south-pole of sufficient strength on chip or north-pole of sufficient strength under chip, the CXHA3161 will turn on the OUT output.CXHA3161 series have above two kinds Hall effect output,
please select appropriate model for different application.While the magnetic flux density (B) is larger than operate point BOP, the OUT will be turned on (low), the output is
held until B is lower than release point BRP, then turned off(high).
