I will pass this on to the team, seems like the documentation needs to be updated.

So this is not a single button mode at all. I was expecting single button mode to mean both using one button. This functionality is useless. It is single operation mode, not single button.

Nguyen,

I got a correction from the R&D team, we are having an internal ticket to update the documentation for this.

If the SHPHLD pin is configured to enter ship mode at 2s press, then you will lose the reset functionality. It will be in ship mode after 2s press and will be waiting for wakeup signal, so basically nothing happens at 10s mark. If you want to keep the reset functionality with the long press, you can disable the power off functionality from the SHPHLD pin (PWRBUTTON sticky bit), then it will not go to ship mode at 2s press and you can reset it with 10s press. But entry to the ship mode must be done with I2C write in this case.

You are right, I had to read that sentence again. Sorry for using "explicitly" as it is not that explicit. I will pass this to the tech writers team. Thank you.

Thanks for the info. What is written in the datasheet part I know. Nothing in the datasheet mention that ship mode still available. Hence the question. Please change datasheet to include what you mentioned here.

Hi Nguyen,

it’s explicitly documented in the nPM2100 datasheet. In the Single-button configuration section (7.5 Reset, page 72), it says:

“This enables a single button to be used to exit Ship mode, and as a reset button through a long press. This configuration disables reset button functionality from pin PG/RESET.”

In other words, Ship mode (2 s press on SHPHLD) remains fully available; holding the same pin longer (t_RST_DEB_L, 10 s default) simply invokes the power-cycle reset. You could do a quick 2 second hold on SHPHLD puts the device into (or wakes it from) Ship mode. If you keep holding past the 2 seconds up to roughly 10 seconds, it will instead perform a full power-cycle reset.
