说明

TPS36-Q1 是一款超低功耗(典型值为 250nA)器件,可提供具有可编程窗口看门狗计时器的精密电压监控器TPS36-Q1 支持用于欠压监控的宽阈值电平,在额定温度范围内的精度为 1.2%。

TPS36-Q1 可提供具有多种功能的高精度窗口看门狗计时器,广泛适用于各种应用。关闭窗口计时器可以由工厂编程或用户使用外部电容器进行编程。可以使用逻辑引脚的组合来动态更改打开窗口与关闭窗口的比率。看门狗还提供独特的功能,例如启用/禁用、启动延迟、独立的 WDO 引脚选项。

RESETWDO 延迟可设定为出厂编程的默认延迟设置或通过外部电容器进行编程。该器件还提供锁存输出操作,监控器或看门狗故障清除之前会锁存输出。

TPS36-Q1 提供了 TPS3852-Q1 器件系列的性能升级替代米6体育平台手机版_好二三四。TPS36-Q1 采用小型 8 引脚 SOT-23 封装。
