TPS25751A: Sleep Mode Current Consumption and CC Pin Wake-Up Functionality

Hello,

Hori Shota said:

Can we consider that the device consumes only 56 µA in Sleep Mode?

Yes.

Hori Shota said:

Does this current consumption include the circuitry required to keep the wake-up function active, such as monitoring the USB Type-C CC pins?

Yes.  https://www.ti.com/lit/ds/symlink/tps25751a.pdf#page=49

Hori Shota said:

In other words, is the 56 µA current mainly consumed to maintain the wake-up detection capability while the device remains in Sleep Mode?

Yes, the PD controller maintains wake-up detection during sleep.  Please see the description of activity in the Power states Section, 8.4.1. https://www.ti.com/lit/ds/symlink/tps25751a.pdf#page=49

Therefore, can we say that the total current consumption in Sleep Mode is 58 µA (2 µA + 56 µA)?

Yes.  This is correct.
