Hi, I'm trying to understand if we can use the Sleep state in our application to save current when we're powered down. The gauge requires 250uA when active and 100uA when in Sleep, so going to Sleep would help our battery last longer when the product is not in use over a period of a few weeks.
As I understand it, in Sleep mode the DSG FET is always disabled. It seems to me that this means no current can flow out of the battery pack. The gauge can be woken up if the Master communicates to it on I2C, but it seems like in most cases the Master would probably be shut down and unable to get power if the DSG FET is off? There is also a Wake comparator circuit that monitors the current into or out of the battery pack and can wake the gauge that way, but again, how can any device draw current if the DSG FET is off?
I'm sure I have some misunderstanding, can you please help explain it to me?
Thanks,
Arthur
