- RST 状态可以保持以用于裕度调节
- 低电源电流：30μA (典型值)
- 具输入干扰免疫力
- 可调复位超时周期
- 可选择的内部超时节省了组件
- 节省空间的 8 引脚 TSOT-23 封装和 3mm x 2mm DFN 封装
LTC®2911 是一款具有一个电源故障比较器的低功率、高准确度、三通道电源监视器。复位超时可以利用一个外部电容器来选择，或设定至一个在内部产生的 200ms。
V1 引脚用于监视一个 3.3V 电源。V2 引脚负责监视一个 5V、2.5V、1.8V、1.2V或可调电源。第三个可调输入具有一个 0.5V 的标称门限，因而允许利用一个阻性分压器来配置其门限。所有三个比较器在整个工作温度范围内均具有一个 1.5% 的严格门限准确度，而一个干扰滤波器则用于确保可靠的复位操作。
一个备用的比较器可通过配置以提供低电压情况的预警。当 PFI 输入的电压降至 0.5V 以下时，它将导致 PFO 输出拉至低电平，因而允许利用一个阻性分压器来配置电源故障门限。TMR 引脚上提供的一种锁存功能使得能够对 RST 输出进行锁存以防止系统复位，从而简化了裕度测试。
