Pin-Selectable Watchdog Timers

General Description The MAX6369–MAX6374 are pin-selectable watchdog timers that supervise microprocessor (µP) activity and signal when a system is operating improperly. During normal operation, the microprocessor should repeatedly toggle the watchdog input (WDI) before the selected watchdog tim

引脚可设置看门狗定时器

MAX6369–MAX6374均为引脚可选的看门狗定时器，用于监控微处理器(µP)活动并在系统工作不正常时发出信号。在正常工作期间，微处理器应在选定的看门狗超时周期到期之前反复切换看门狗输入(WDI)，以证明系统正在正确处理代码。如果µP在超时周期到期之前未提供有效的看门狗输入跃迁，则监控器会置位看门狗（低电平有效WDO）输出，以表明系统未在预期时间范围内执行所需指令。看门狗输出脉冲可用于复位µP或中断系统以发出处理错误警告。\n\n MAX6369–MAX6374均为灵活的看门狗定时器监控器，可通过代码执行错误通知提高系统可靠性。该系列提供多种引脚可选的看门狗定时选项，以适合广泛的 • 用于关键µP应用的精密看门狗定时器\n\n• 引脚可选的看门狗超时周期\n\n• 引脚可选的看门狗启动延迟周期\n\n• 无需断电重启即可更改看门狗时序特性\n\n• 开漏或推挽脉冲低电平有效看门狗输出\n\n• 看门狗定时器禁用功能\n\n• 工作电压：+2.5V至+5.5V\n\n• 低电源电流：8µA\n\n• 无需外部元件\n\n• 微型8引脚SOT23封装\n\n• 通过AEC-Q100认证（仅MAX6369KA/V+和MAX6374KA/V+）;
