The Great Search: DS18B20 and other 1-Wire interface chips
We just wrapped up our breakout board design for the DS2484 (https://www.digikey.com/en/products/detail/analog-devices-inc-maxim-integrated/DS2484R-T/5020823)an I2C to 1-Wire device, and we had someone ask "what is 1-Wire, and when should I use it?"
