CXHA3157 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 CXHA3157will turn on the NOUT output.While the magnetic flux density (B) is larger than operate point BOP(n), the NOUT will be turned on (low), the output
is held until B is lower than release point BRP(n), then turned off (high).
