FS7867S是一款应用于数字系统供电电源电压监控的电压检测芯片
2022-07-04 12:48:00 【51CTO】
概述
微处理器电压检测复位芯
FS7867S是一款应用于数字系统供电电源电压监控的电压检测芯片,可在工业级标准温度范围内工作。
FS7867S产生一个复位信号,当系统电源电压降低到设定值时复位信号变低,当系统电源电压恢复到设定值之
芯片会在至少140ms的延迟时间之后将复位信号置高。FS7867S系列产品可以提供任意客户需要的设定检测电压值
目前我们会提供7个针对5.0V, 3.3V, 3.0V和2.5V四类电源电压的标准工业用电压监测值。
FS7867S提供推挽结构的输出级,当待监测电压高于设定电压值时复位输出高电平。
快速的电源瞬态的抖动和毛刺会被本芯片滤除而不会导致误动作,同时即便供电电压低至L0V也能够保证正常
输出逻辑和各性能指标。
FS7867S提供紧凑的3脚封装形式S OT-23和SOT-23-3L.
