bq24250 fault state

PAN-M

Dear all.

The TS fault is only "Battery over temp" in P30 of a datasheet.
Is cold state same?
When the temparature is between VCOLD and VCOOL, is Termination current disable?

Going above T_HOT (below V_HOT), and below T_COLD (above V_COLD) will result in a TS fault.

And correct, termination is disabled between V_COLD and V_COOL.

Joel
Is that the TS fault mode Register#6(B0:B2) meaning?
Can I ignore "(Batter Over Temp)"?

Hey PAN-M,

REG #6 [2:0] tells you what state the NTC is reporting of the battery.

This is used to determine "Battery Over Temp", unless you disable TS function (Reg #6 [3].

If you disable TS function, you can ignore the over temp,

if you keep TS enabled and the battery temperature is between T_COLD and T_HOT

I'd like to reconfirm you answer.
Your answer is "Going above T_HOT (below V_HOT), and below T_COLD (above V_COLD) will result in a TS fault."
About "below T_COLD (above V_COLD) will result in a TS fault.", where is this sentense written?
We had understanding that "TS Fault (Batter Over Temp)" was "Battery over temp(above T_HOT)". (Batter=Battery)

"TS Fault (Batter Over Temp)" = "Going above T_HOT (below V_HOT), and below T_COLD (above V_COLD) will result in a TS fault." ?
Is "Over" the meaning of the high temperature side and the low temperature side?

Hello PAN-M,

It may sounds a bit misleading, so we will take your feedback to perhaps improve the wording of the datasheet.

However, when we say over-temp, we mean over the temperature specification, so below Tcold or above Thot.

Hope this clarifies your customer's concern.

Thank you.
I could understand clear.
