Glasgow/master f8afe86 whitequark: Allow programming a non-volatile voltage limit, as a safety feature....
03:22
<
azonenberg >
whitequark: i love design features like that
03:22
<
azonenberg >
safety limits you can configure for a given deployment that keep it from doing something stupid
03:23
<
azonenberg >
my R&S PSUs have that
03:23
<
azonenberg >
you can set a limit for voltage or current and the interactive adjustment dial refuses to go beyond that
03:23
<
whitequark >
it even protects you against DAC/LDO failure, assuming you're smart enough to connect Vsense to the target
03:23
<
whitequark >
well, and assuming it is still able to disable the DAC/LDO
03:24
<
whitequark >
so it's
*two* layers of safety
