LTC2956 是一款具按钮控制功能的微功率、宽输入电压范围、可配置唤醒定时器。其周期地唤醒和接通一个连接系统以执行诸如监视温度或捕获图像等任务。在完成任务之后,LTC2956 关闭系统以节省电能。
唤醒定时器周期可采用配置电阻器在 250ms 至 39 天之间进行调节。系统唤醒时间可利用 SLEEP 引脚上的输入脉冲来控制,或由 ONMAX 引脚上的电容器来调节。LTC2956 能在 1.5V 至 36V 的宽电源输入范围内运作。800nA 的低静态电流适合于电池供电型应用。
按钮输入允许用户进行唤醒定时器的停机、接通或复位操作。当定时器处于停机模式时,静态电流减小至 300nA。另外,LTC2956 还提供了三个状态输出以指示模式切换和按钮事件。该器件可提供两种版本,以适合需要正使能极性或负使能极性的应用。

DC2254A-B:LTC2956-2 Demo Board | Wake-Up Timer with Pushbutton Control, EN Pin
Demonstration circuits 2254A-A and 2254A-B feature the LTC2956-1 and LTC2956-2, respectively. The LTC2956 is a micropower, wide input voltage range, configurable wake-up timer with pushbutton control. It periodically wakes up and turns on a connected system to perform tasks like monitoring temperature or capturing images. After completing the task, the LTC2956 turns the system off to conserve power. The wake-up timer period can be adjusted from 250ms to 39 days.
