applications in which such temperatures are likely, it is strongly recommended that VDD be applied to the
DS18B20.
For situations where the bus master does not know whether the DS18B20s on the bus are parasite
powered or supplied with external VDD, a provision is made in the DS18B20 to signal the power supply
scheme used. The bus master can determine if any DS18B20s are on the bus which require the strong
pullup by sending a Skip ROM protocol, then issuing the read power supply command.
After this
command is issued, the master then issues read time slots. The DS18B20 will send back “0” on the 1-
Wire bus if it is parasite powered; it will send back a “1” if it is powered from the VDD pin. If the master
receives a “0,” it knows that it must supply the strong pullup on the DQ line during temperature
conversions. See “Memory Command Functions” section for more detail on this command protocol.
