LN4917
■ General Description
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).

LN245
LN245 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，LN245 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。 LN245 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。 -
