概览

MAX803/NCP803 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,该时段通过系数进行微调。MAX803/NCP803 具有一个开路有效低电平 RESET(bar) 输出。MAX803/NCP803 的输出在低至 VCC = 1.0 V 下可保证有效,采用 SOT-23 和 SC-70 封装。MAX803/NCP803 适用于抑制 VCC 线路上的快速瞬变差错。0.5 µA (VCC = 3.3 V) 的低电源电流使得此器件适用于电池供电应用。
