电压监督,3 引脚,为处理器,极低电源电流,重置监控

Favorite

概览

MAX809/NCV809 和 MAX810 是一款成本高效的系统监督电路,用于监控数字系统中的 VCC,必要时为宿主处理器提供重置信号。无需外部组件。重置输出通过重置电压阈值,在 VCC 下降 10 µsec 内驱动为有效。重置将在 VCC 上升至重置阈值以上之后一个超时时段内保持有效,该时段由工厂进行微调。MAX810 是有效高电平 RESET 输出,而 MAX809 为有效低电平 RESETbar 输出。两个器件均采用 SOT-23 和 SC-70 封装。MAX809/810 适用于抑制 VCCline 上的快速瞬变故障。0.5 µA (VCC = 3.3 V) 的低电源电流使得这些器件适用于电池供电应用。
