Hey #electronics lazyweb #AskFedi, does anyone know what the WCH CH224 family does if you configure the sink to request 20V but the source can’t do that? Specifically I’d like to know how it responds to both a “dumb” 5V source, and a PD source that only goes up to 12V.

@jpm it defaults to 5V output, but the “PG” LED doesn’t go off IIRC.
(Ping @Unixbigot I suspect you’ve (ab)used CH224’s extensively)
@jpm hmmmn, i think I have some but i dont think i’ve used them yet. Lemme check.
