产品介绍


ES249低功耗高灵敏度单极型霍尔开关


1. 概述


ES249 是一款基于混合信号 CMOS 技术的霍尔效
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,ES249 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
大的电路周期性地进入“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,则输出晶体管被驱动并转
变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。
当垂直于霍尔传感器的南极磁场超过工作点时,ES249 输出晶体管转变为低电平(输出导
通),导通后输出电压是 VDS。当磁场减弱到低于释放点 BRP时,输出晶体管截止(输出高电平)。
磁场工作点与释放点之间的差距为器件的磁滞(BHYS)。内置磁滞防止了在转换点附近的输出振
荡,而且即使在外部机械振动和电器噪声的情况下也能得到清晰的输出转换。
