I'm trying to figure out what worst case tBG is to resolve a timing issue where tBG > tPOR, as described on page 61 of datasheet. From figure 28 on page 26 of datasheet, tBG is related to R1*22uF.
Which value is appropriate for R1 to use to calculate tBG when we're using an external voltage reference(REF5050)?
Is there any advantage to using 5RC as tBG? It seems that only 2.5 time constants is needed for the bandgap to reach 1.1V. I could see longer time constant being good for dealing with tolerance on the 22uF capacitor.
