产品介绍




1. 概述


EST248D 是一款基于混合信号 CMOS 技术的全极
型霍尔效应传感器,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,EST248D 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,芯片被周期性地“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“工作点”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。
EST248D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(BOP)

状态,而在无磁场时锁定在关(BRP)状态。
