TPS2492: We plan to use TPS2492PW, so we have same question.

Part Number: TPS2492


We plan to use TPS2492PW, so we have same question，

1. What does it do after the timer of TPS2492PW is charged in power limit？

2.What are detail process and time sequence of TPS2492 to turn off the external FET in power limit?

3. How does TPS2492 go into F_TIRP mode？What is the condition or threshold value in F_TRIP mode which TPS2492 is go to?

4. If the TPS2492 is in power limit trip，the max current limit threshold is fixed 33mV or not？And if not， How calculate the current limit threshold in power limit trip？

5. What is power limit mode，and how to use it? Which condtions will trigger the TPS2492 into power limit?

6. ELECTRICAL CHARACTERISTICS in page 3 ：current limit threshold V(VCC-SENSE) with power limiting trip --25mV.

Question：Current limit threshold V(VCC-SENSE) will be 25mV when tps2492 is working in power limit mode？And if not, how to set Current limit threshold V（VCC-SENSE）?

7. DETAILED PIN DESCRIPTION in page8：PROG; the voltage applied to this pin（0.4vminimum）program the power limit used by the constant power engine.

Question：Power limit PLIM=VDS*IDS？

Thanks！
