We are using the DA14583 in a smart button and currently have a custom power management circuit that shuts down the DA14583 completely.
The down side is that we are unable to "catch" fast clicks (input signal duration 50 - 200ms). We guess this is due to the boot sequence of the DA14583.
We have also considered using the extended sleep mode but are concerned about power consumption.
The button should run on a CR2016 for at least a year. Is this possible using the extended sleep mode?
What is the power consumption in extended sleep mode?
Can we read inputs with a signal duration of 50 - 200ms while in extended sleep mode?
