Hi Yihe,

The total current consumed by LM3880 while powered, but when the enable pin is unasserted.

We are trying to optimise battery life.

Kind regards,

If you try to saving the battery life, the pull up souce of the flag output shall not be the same source to power LM3880. otherwise, the current consumption would be much higher than EN pin is asserted case.

if the EN is de-asserted and flags have pull up from other source, the total current is very close to the operating quiescent case.
