soft-start powersupply and controllers | | 01/01/70 00:00 |
supervisor chip or processor with good brownout detection | | 01/01/70 00:00 |
Per gives a good solution if you can tolerate restarts | | 01/01/70 00:00 |
Long rise times of Vcc are critical! | | 01/01/70 00:00 |
replace the 7805 | | 01/01/70 00:00 |
Lot of information | | 01/01/70 00:00 |
look at PowerTrends (TI) | | 01/01/70 00:00 |
Some answers... | | 01/01/70 00:00 |
Bigget reset capacitor and resistor | | 01/01/70 00:00 |
it is NOT the capacitor value | | 01/01/70 00:00 |
Thanks Erik | | 01/01/70 00:00 |
I partially disagree | | 01/01/70 00:00 |
disagree with what? | | 01/01/70 00:00 |
With thinking only in a reset chip. | | 01/01/70 00:00 |
Use the reset chip to reset the powersupply | | 01/01/70 00:00 |
How about $0.15 | | 01/01/70 00:00 |
A small clarification | | 01/01/70 00:00 |
3 pin regulators with uvlo | | 01/01/70 00:00 |
Eh ? | | 01/01/70 00:00 |
Only a clarification | | 01/01/70 00:00 |
Steve, I meant turning on MCU supply | | 01/01/70 00:00 |
and power down | | 01/01/70 00:00 |
Erik, brown-out is handled by Silabs MCU!! | | 01/01/70 00:00 |
Did I miss that? | | 01/01/70 00:00 |
But Erik... | | 01/01/70 00:00 |
In application notes, direct pull-ups have been used... | | 01/01/70 00:00 |
some idiot, not there any more ... | | 01/01/70 00:00 |
You seem to be wrong about the capacitor, Erik | | 01/01/70 00:00 |
Not necessarily... | | 01/01/70 00:00 |
the risetime has nothing to do with reset ... unless | | 01/01/70 00:00 |
which SiLabs part? | | 01/01/70 00:00 |
Andy.. | | 01/01/70 00:00 |
SILabs urban legends | | 01/01/70 00:00 |
Interesting... | | 01/01/70 00:00 |
you may | | 01/01/70 00:00 |
Thank you, I really appreciate it! | | 01/01/70 00:00 |
Clarifying, Erik, Kai | | 01/01/70 00:00 |
The reset from the supply monitor will be there | | 01/01/70 00:00 |
Good advice... | | 01/01/70 00:00 |
I am guilty of not recalling all differences | | 01/01/70 00:00 |
Only open-drain but not push-pull! | | 01/01/70 00:00 |
Good one, Kai | | 01/01/70 00:00 |
why the 'love' of the MAX1232? | | 01/01/70 00:00 |
True, Erik | | 01/01/70 00:00 |
Have you seen this post? | | 01/01/70 00:00 |
Have you seen this post? | | 01/01/70 00:00 |
Turn on your brain, Erik, and read what I wrote! | | 01/01/70 00:00 |
a picture is worth 1000 words | | 01/01/70 00:00 |
So you haven't read the words?? | | 01/01/70 00:00 |
I was suggesting him the MAX1232... | | 01/01/70 00:00 |
Well, even more demanding... | | 01/01/70 00:00 |
Bigger, not bigget | | 01/01/70 00:00 |
Only external electronics can help you | | 01/01/70 00:00 |
Scheme to provide fast turn-on after full discharge | | 01/01/70 00:00 |
