Hi Team,
I have some question regarding RVSET on DRV3220.
1. Can measure the die temperature via SPI register value? I can't find it on datasheet.
2. What is Max output current/voltage value from RVSET pin? Customer doesn’t want to know the Max rating on RVSET pin. They want to know what voltage or current can be occurred from RVSET pin because she concern MCU damage if RVSET pin is connected to MCU directly.
3. For low temperature as -40℃, will same formula be adopted?
Die Temp’=(1.6141V – RVSET voltage) / 3.3mV
4. I think that we can use RVSET for two purpose as ① to set up ADREF/VDDIO overvoltage and undervoltage ② to check relative IC temp’. Do you have another reason for RVSET pin except two purpose?
5. Are you accept to measure die temperature with RVSET pin voltage? I don’t want to recommend RVSET measurement in order to measure exact di temperature on DRV3220 because the RVSET is not meant to give the exact temperature and is more of a relative measurement compared to room temperature for each unit.. Need your advice.
Thanks
Anthony Kim
