CXFA3117先进CMOS工艺超灵敏极独立的霍尔效应开关有锁存数字输出磁通量的北极或南极都会打开输出斩波稳定放大器2.5伏到3.5伏电池应用的微功率操作

CXFA3117集成电路是一种超灵敏、极独立的霍尔效应开关，具有锁存数字输出。一个2.5伏到3.5伏的操作和一个独特的时钟方案降低了平均操作功率的要求，无论是一个有足够磁通量的北极或南极都会打开输出；在没有磁场的情况下，输出是关闭的。极性独立和最小的功率要求，使该设备很容易取代簧片开关优越的信号调节。采用先进的CMOS工艺，充分利用了低电压、低功耗的要求，SOT-23封装为大多数应用提供了优化的封装。
电池应用的微功率操作
·斩波稳定放大器
·独立于南北极磁铁，易于制造

The CXFA3117, integrated circuit, is an ultra-sensitive, pole independent Hall-effect switch with a latched digital output. A 2.5 volt to 3.5 volt operation and an unique clocking scheme reduce the average operating power requirements, either a north or a south pole of sufficient flux will turn the output on; in the absence of a magnetic field, the output is off. The polarity independence and minimal power requirement allow this device to be easily replaced reed switch for superior for signal conditioning. Advanced CMOS processing is used to take advantage of low-voltage and low-power requirements, SOT-23 package provides an optimized package for most applications.
