■ General Description LN4916 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 south-pole of sufficient strength on chip or north-pole of sufficient strength under chip, the LN4916 will turn on the SOUT output. While the magnetic flux density (B) is larger than operate point BOP(s), the SOUT will be turned on (low), the output is held until B is lower than release point BRP(s), then turned off (high). ■ Package SOT-553 ■ Features 2.0V to 4.5V battery operation Operation with South Pole Chopper stabilized Superior temperature stability Extremely Low Switch-Point Drift Insensitive to Physical Stress Good RF noise immunity ESD HBM bigger than 4kV Lead Free Finish/RoHS Compliant ■ Application Mobile phones and Portable electronic devices Notebook
