MAX16998

High-Voltage Watchdog Timers with Adjustable Timeout Delay

General Description The MAX16997/MAX16998 are microprocessor (µP) supervisory circuits for high-input-voltage and low-quiescent-current applications. These devices detect downstream circuit failures and provide switchover to redundant circuitry. See the Selector Guide for the different versions

MAX16998

高压看门狗定时器,可调节超时周期

MAX16997/MAX16998是应用于高输入电压、低静态电流系统的微控制器(µP)监控电路。这些器件用于检测下游电路的故障,以切换到冗余电路。有关该系列产品不同版本,请参考数据资料中的Selector Guide。\n\n MAX16997/MAX16998系列具有4路独立输入,可实现复位和看门狗功能。其中,SWT和SRT输入通过外部电容独立设置看门狗超时周期和复位定时器。RESETIN/EN监控各自的输入电压。电阻分压器用于设置复位门限。\n\n MAX16998A/B/D产生/RESET和/ENABLE两路输出信号。只要RESETIN跌落至门限电压以下或在WDI端检 • 宽泛的输入电压范围:5V至40V\n• 18µA静态电流(+125°C,典型值)\n• 电容可调超时周期,用于看门狗和复位定时器\n• 看门狗定时器窗口选项(MAX16998B/D)\n• 监测外部电压(RESETIN用于MAX16998A/B/D,EN用于MAX16997A) \n• EN输入电压与汽车电池一致\n• TTL和CMOS兼容漏极开路输出\n• 18V最大漏极开路复位输出电压\n• 28V最大漏极开路使能输出电压\n• 上电/断电复位功能(MAX16998A/B/D)\n• 通过AECQ-100认证\n• -40°C至+125°C工作温度范围\n• 小型(3mm x 3mm);
