Hi, I have a design that uses the ADM1064 super-sequencer device. Whilst tracing a fault with another device, I observed that two of the power supplies, controlled by the ADM1064 were glitching on...
View ArticleHow do I clamp output of voltage supervisor circuit to 0.0V until power is good?
I need a POR circuit monitoring 3.3V, but I need the output to be guaranteed all the way down to 0.0V VCC. Typical circuits have the output rise up to perhaps 1V as power rises to 1V, then the circuit...
