BMP388 power management 10mS ramp-up

[Kra70s]

Hi Bosch Sensortec Community, We're developing a PCB with one of your sensors, the BMP388.

In the chapter 3.2 regarding power management, there It says that "The slope for ramp up time must not be less than 10 ms"

But we cannot achieve this point since the LDO that we're using it doesn't have a soft start ramp-up feature

Can you please explain to me what's the drawback and what could be the issues if we cannot achieve this point?

We haven't had any issues so far on our prototypes, but we're wondering If we could have anyone in the future.

It would be super nice if you could help us 🙂

Hi,

Thanks for your inquiry.

Sorry for the typo in BMP388 datasheet. In the chapter 3.2 regarding power management, the right statement should be "The slope for ramp up time must not be less than 10 us and no more than 10ms" in order to have proper power-on reset. We will update the datasheet soon.

Thanks.
