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).

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).

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).

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).

LN4923 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 LN4923 will turn on the OUT output. When south-pole of sufficient strength on chip or north-pole of sufficient strength under chip, the LN4923 will turn on the OUT output. 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). LN4923 series have two kinds Hall effect output, please select appropriate model for different application.

LN4915 是一款基于混合信号 CMOS 技术的无极性霍 尔开关，这款 IC 采用了先进的斩波稳定技术，因而能够提 供准确而稳定的磁开关点。 在电路设计上，LN4915 提供了一个内嵌的受控时钟机 制来为霍尔器件和模拟信号处理电路提供时钟源，同时这个 受控时钟机制可以发出控制信号使得消耗电流较大的电路周 期性的进入“休眠”模式；同样通过这个机制，芯片被周期 性的“唤醒”并且根据预定好的磁场强度阈值检测外界穿过 霍尔器件磁场强度的大小。如果磁通密度高于“操作点”阈 值或者低于“释放点”阈值，则开漏输出晶体管被驱动并锁 存成与之相对应的状态。而在“休眠”周期中，输出晶体管 被锁定在其先前的状态下。在电池供电应用中，这种设计对 于延长工作寿命提供了最好支持。 LN4915 的输出晶体管在面向封装标示一面存在一定强 南极或北极磁场时被锁定在开状态，而在无磁场时锁定在关 状态。 LN4915 比 LN4913 具有更高的磁场感应灵敏度，可实 用于安防系统、感应磁体较小的场合。
