【产品】集成了可编程看门狗定时器的SGM820精确电压监控器，电压阈值精度＜1%

时间： 2019-08-27 来源：SGMICRO

技术问答

SGMICRO（圣邦微电子）的SGM820结合了一个精确的电压监控器和一个可编程看门狗定时器，适用于监控1.8V、2.5V、3V、3.3V和5V共模电压。SGM820比较器的欠压阈值具有很高的精度（-40℃至+125℃范围内），还包含精确的迟滞，是严格容差系统的理想选择。该监控器的nRESET延迟具有精度高，且具有高精度延迟定时。

SGM820包含一个可编程的看门狗定时器，适合多种应用。专用的看门狗输出（nWDO）能够提高分辨率，有助于确定故障情况的性质。看门狗超时可以通过外部电容编程，也可以采用工厂编程的默认延迟设置。可以通过逻辑引脚禁用看门狗，以避免在开发过程中出现不必要的看门狗超时。

SGM820采用TDFN-3×3-8L和TDFN-2×2-8L绿色封装，其工作环境温度范围为-40℃至+125℃。
