Hi team,

1) Is "T1(Temp Warm)" threshold, shown in Figure 10-11, corresponding to "VTS = 0.5 × VSENSE" and "VTEMP_WARM"?

2) Is "T2(Temp Hot)" threshold, shown in Figure 10-11, corresponding to "VTS = 0.65 × VSENSE" and "VTEMP_HOT"?

Hi Kuno,

Thank you. Please see lower. All of "T1(Temp Warm)", "VTS = 0.5 × VSENSE", "VTEMP_WARM", "T2(Temp Hot)", "VTS = 0.65 × VSENSE", and "VTEMP_HOT" are reference to "10.3.10 Thermal Management With Temperature Sensing (TS) and OTSD" shown in TPS25854-Q1 datasheet.

Hi Ochi-san,

Yes, you are correct, we will detect the TS voltage, to device the Temp Warm or Temp Hot, and the threshold just like you said, T1(Temp Warm)", "VTS = 0.5 × VSENSE", "VTEMP_WARM", "T2(Temp Hot)", "VTS = 0.65 × VSENSE", thank you.

Best Regards,
