nRF54L05 power consumption at sleep mode but comparator still working

[Eric Duong]

Hi,

For a meter application with battery, I want MCU is sleeping but comparator still working to count a pulse input (freq <100khz)

Can Nordic IC can support this idea and how power consumption at this stage?

Thanks,

Brgs,

Eric.

Hi,

Do you want the Comparator to wake up the device from sleep?

Can Nordic IC can support this idea and how power consumption at this stage?

I will have a look and see what I can find on this.
Will get back to you in January.

Activation is possible, as far as I know in Low Power mode (Deep Sleep), the consumption can be only about <1 µA when using features such as GPIO wake-up, timer interrupt, or PPI enabled features.

Hi,

could you share the example code for this ?

due to 54L05 sample is not available right now, I will test on nrf52833-DK.

Brgs,
