LN4918
LN4918 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 LN4918 will turn on the OUT output. When south-pole of sufficient strength on chip or north-pole of sufficient strength under chip, the LN4918 will turn on the OUT output.
LN4918 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)
