AW: [basicstamps] Re: Battery Backup Question

Archiver

Hi Tracy,

did I miss your answer to the following question or didn't you answer yet?
One thing is for sure: it is not that you wouldn't know.. :-)

Greetings, Uli





do you think this (battery backup with diodes) will be fast enough to work
without resetting when the
power is interrupted abruptly? Could this even be some kind of
brownout-prevention? Are there diodes that suit this purpose better (in
other words: faster diodes)?

Thanks, Uli

As Jim pointed out,, the diode switches in about a microsecond, and
in this circuit there are usually capacitors breeze the circuit
through the transition. Yes, it is good brownout protection.
