The NHS3152 IC has a sleep and deep sleep power savings modes. But no description as the reduction in power when these modes are enabled. Any guidance?

Hello @bmeyer ,

 

There is no detailed documentation on these power modes, the power gain compared to deep-power down is limited.
The difference between sleep and deep-sleep is only the handling of the EEPROM.

The power gain is dependent on the Sysclk frequency, as can be seen below in a graph of a typical application.
More power can be conserved by slowing down the Sysclk.

There is a slight increase of the Idd current (up to +12uA) when the Vdd voltage drops below 2.2V.

Hope that helps,

 

Have a great day,
Kan

Hello Kan:

Thanks for the guidance. However, this doc still only details current consumption during active and deep power down. Doesn't mention current consumption during sleep and deep sleep.
