It can accurately handle very long timers that a traditional RC style timers (think 555 timer) wouldn’t be able to do.

To see if this chip will work for my application I picked up the DC2254A-A evaluation board.

The box the DC2254A-A evaluation board comes in.

Inside the box.

The Evaluation Board

Here is the datasheet for the evaluation board.

For my use case, I am going to pull ONMAX to GND which will disable the timer that turns off the AWAKE timer. I will toggle the Sleep pin from low to high to low to reset the timer.

Seems to work!
