Can anyone explain to me how, in using a one-wire in parasitic mode, you can be providing power and sending a signal out the same terminal?
For instance, I've been involved in a project using a thermocouple IC in a TO-92 package that uses parasitic power. If you have a serial data bus that provides power through the data bus, you only need the output terminal and ground terminal of the TO-92 for it to function. You can also get a version with a dedicated VDD terminal, which makes a lot more sense to me currently.
Thanks!
