NRF52832 POR / Brown Out

[Bwalker]

I'm working on an NRF52832 product that will be intermittently powered, and the supply rail may fluctuate slowly, drifting above and below 1.8V.

I saw this post:

And wanted to check if this applied to the NRF52832 (adding a 1M resistor between reset and gnd)

Hi

We haven't had any reports on the POR or Brown Out failing in the nRF52 series, so a larger pull-up resistor should not be necessary. If you wish to do so anyway, it shouldn't be a problem either (except increasing current consumption somewhat), so it's entirely up to you.

Best regards,

Simon
