Part Number:BQ24040

Hi, Ti friends,
Please refer to the attached file of the experiment report and please help to confirm the questions as below, thank you.
•The experiment results tell us,

•1. The /CHG state is very different when TS voltage is changing especially in cold fault and hot fault on different battery voltage (example: >= 4.06V or < 4.06V).
The software can’t judge the status. Could you please help to confirm it ?
•2. When the battery voltage is >= 4.06V condition,
it seems the /CHG is always on the high state when the temperature increased from normal temp. to hot temp. or started from hot temp. Is it correct ?
•3. When the battery voltage is < 4.06V condition,
it seems the /CHG is always on the Low state once the temperature go into normal temp. Is it correct ?
•4. Refer to the datasheet, page 18, mention about Charging state, TEMP FAULT, “ON for 1st Charging”, could you please explain more about that?
Thank you.
KY.
