nRF52840 errata 197 workaround options

[mstevens]

Hello support team,

I am using your product through a module vendor and I have a question regarding errata 197.  If the DC/DC regulator only has problems in low power states, would it be considered a valid workaround to put it in LDO mode before going into such a state, and back to DC/DC mode when coming out?

Hi there,


AndreasIs there silicon available with this bug fixed?

I have the same problem in a new wearable design with the nRF52840.

Cheers,

Hi Casper,

 

Not yet, it will be in Q1 next year. For more detailed answer you should contact the Nordic Regional Sales Manager, responsible for your area.

 

Best regards,

Andreas
