DESCRIPTION
The DS1821 can function as a standalone thermostat with user-programmable trip-points or as 8-bit
temperature sensor with a 1-Wire digital interface. The thermostat trip-points are stored in nonvolatile
memory, so DS1821 units can be programmed prior to system insertion for true standalone operation.
The DS1821 has an operating temperature range of 55癈 to +125癈 and is accurate to ?癈 over a range
of 0癈 to +85癈. Communication with the DS1821 is accomplished through the open-drain DQ pin; this
pin also serves as the thermostat output.
