3..3V 關P Power Supplly Moniittor and Ressett Ciircuiitt

The IMP1832 microprocessor supervisor can halt and restart a “hung-up” or “stalled” microprocessor, restart a microprocessor after a power failure, and debounce a manual push-button microprocessor reset switch. The IMP1832 features over 40 lower supply current than the pin compatible Dallas Semico

3.3V 低功耗监控

IMP1832微处理监控器能暂停和重启一个\"有障碍\"或\"停转\"的微处理器，在电源失效后重启一个微处理器并且增加了一个具有防误操作的手动微处理器复位按钮。低功耗的监控器 比Dallas半导体公司的DS1832器件低 40%供给电流。\r\n\r\n 精确温度补偿基准和比较电路能监控3/3.3V,VCC的输入电压。在接通电源或当VCC 电源超出可选择精确值的范围时，两个高、低电位复位输出启动就被激活。当VCC升到阈值电压之上时，复位信号启动并持续保留至少250毫秒，使电源和系统的微处理器得到稳定。跳闸点精确度信号及精度选择可以把跳闸等级精确度选择为10％或20％\r\n\r\ · 经精度选择针脚，使用者可选择阈值精确度 \r\n　　o 2.97V最大阈值的10％及2.64V最大阈值的10％ \r\n· 经TD脚的可选择看门狗计时器周期: 150毫秒/610毫秒/1.2秒 \r\n· 比Dallas低40% 电流\r\n　　o IMP最大20毫安 比 Dallas的35毫安 \r\n· 双重复位输出: 低电位启动（开漏）及高电位启动 \r\n　　o 最小复位周期为250毫秒 \r\n· 8-脚封装选项：DIP、 SO和缩小的MicroSO \r\n· MicroSO的封装脚比SO小 50% \r\n· 防误操作手动复位脚;
