Hi, Ti member
I am using Bq76940 external and internal temperature sensor.
Q1. I found even use 2 sec after [TEMPSEL] change, still has chance to got the wrong temp. reading. How can I make sure it switched.
Q2. For Die temp sensor. I test it has a high offset error. Is that have any tolerance specification? Or statistical data?
Q3. If I send BOOT signal under an already running IC, What will I get the TSx reading right after (< 2sec) BOOT signal? 0? Random?
Q4. Why Die temperature is so inaccurate?
