SGM820 是一个高精度监控电路系列,它配备了可编程看门狗定时器。该系列提供了多种欠压阈值电压选项,适用于1.8V、2.5V、3V、3.3V和5V系统轨电压监控。此外,SGM820的nRESET延迟具有高精度的延迟时序,并且结合其精确的电压监控滞后,使得SGM820非常适合用于对公差要求严格的系统。
SGM820具备可编程看门狗定时器功能,用户可以通过外部电容或默认的出厂设置来对超时时间进行编程。此外,用户还可以通过逻辑引脚来禁用看门狗定时器,以防止在开发过程中发生意外的超时。
SGM820采用了环保的TDFN-3×3-8L和TDFN-2×2-8L封装,并能在-40℃至+125℃的环境温度范围内正常工作。
