npm1300 entering shipmode while VBUS is present

[dani_martin]

Hi, we are writing the register TASKENTERSHIPMODE to enter ship mode, and everything works ok. But as the ref manual says, when VBUS is present this task is ignored.

Is it possible to change this behavior so the task is executed even is VBUS is present?

Thanks

Hi Dani,

I'm afraid what you are describing is not possible. The purpose of the ship mode is to keep the device completely off, drawing as low current as possible (for example when the device is shipped - hence the name). It does not make much sense to connect the power supply to a device that is not being used for anything.

Can I ask, what is the reason behind your question, what are you tryin to achieve? Maybe I can suggest some alternate solutions to your problem.

thanks for the answer. We are using this mode for the shipment part, but also we want to use it as a general mechanism to put the system in this "almost off mode" in some specific scenarios. In our scenarios, it makes sense to be able to put in this mode even if VBUS is present.

Ok, I see. You can still turn off the LDOs and Buck Regulators through the I2C interface.
