LN4916
MicroPower , Ultra-Sensitive CMOS Hall IC
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).

LN4917
LN4917 is with proprietary Hall effect plate and dual 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 LN4917 will turn on the NOUT output. When south-pole of sufficient strength on chip or north-pole of sufficient strength under chip, the LN4917 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). 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). -
LN4919
LN4919 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 LN4919 will turn on the OUT output. When south-pole of sufficient strength on chip or north-pole of sufficient strength under chip, the LN4919 will turn on the OUT output. LN4919 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). -

LN245
LN245 是一款基于混合信號 CMOS 技術的無極性霍 爾開關，這款 IC 采用了先進的斬波穩(wěn)定技術，因而能夠提 供準確而穩(wěn)定的磁開關點。 在電路設計上，LN245 提供了一個內(nèi)嵌的受控時鐘機制 來為霍爾器件和模擬信號處理電路提供時鐘源，同時這個受 控時鐘機制可以發(fā)出控制信號使得消耗電流較大的電路周期 性的進入“休眠”模式；同樣通過這個機制，芯片被周期性 的“喚醒”并且根據(jù)預定好的磁場強度閾值檢測外界穿過霍 爾器件磁場強度的大小。如果磁通密度高于“操作點”閾值 或者低于“釋放點”閾值，則開漏輸出晶體管被驅(qū)動并鎖存 成與之相對應的狀態(tài)。而在“休眠”周期中，輸出晶體管被 鎖定在其先前的狀態(tài)下。 LN245 的輸出晶體管在面向封裝標示一面存在一定強 南極或北極磁場時被鎖定在開狀態(tài)，而在無磁場時鎖定在關 狀態(tài)。 -
