ADT7302 temp sensor initialisation

Hi EngineerZone,


I'm looking to design in the ADT7302 but interested in what happens when the device is initiated. I'm interested in what happens once the chip initially powers up and what is needed to get the first guaranteed good reading. Also, out of reset, does the chip default to its powerdown mode or is a command needed to take out of powerdown? Would it self-initiate a temperature reading out of reset, or would that need to be explicitly initiated? Also, until that first reading has been completed what value is seen on the SPI? Hopefully you can offer some clarification on this as I can't see anything on the datasheet for this.


Many Thanks.
