Part Number: TPS25981 Other Parts Discussed in Thread: TPS25980 , TPS25982 Tool/software: I have a question. I would like to use this IC in a 12V output voltage line with a 7.5A current limit. Would this IC be a suitable choice? Even if the load tries…
Part Number: TPS25981 Tool/software: Hi team,
TPS25981 is 2mm*2mm package, the Rja is 49.7.
But for TPS259260, it is 3mm*3mm, the Rja is 45.9.
TPS259260 has larger package so the thermal resistance should be lower, correct? But the fact is they are…
Part Number: TPS25981 Tool/software: Hi,
I could not access the SOA graph of the MOSFET inside the IC, TPS259813A.
How can I understand that the MOSFET is in the safe operation area when it is conducting?
Thanks,
Pinar
Part Number: TPS25981 Tool/software: Hi looking as a design in of the TPS259814LRPWR on one of our products but concerned on the pending status of it UL certification quoted on datasheet. Is there an expected time from this will be completed as our product…
Hi Jexy,
Yes, TPS25981 permits assertion at EN for both these cases. Just note that device won't perform startup if Vsupply < Vuvp.

Part Number: TPS25981 Tool/software: Hi,
I fouund 9.1.2 mentioned it can parallel with 2 devices.
May I know what is the maximum parallel limitation for TPS259814?
Thanks!

Hi Andreas,
The device will perform this restart after FFT with 30us delay by design. This is present to ensure any issue like false transients don't cause system down. In your use case, it looks like the FFT is happening and afterwards the device is…
Part Number: TPS25981 Hi,
Does TPS25981x Itimer have maximum capacitance limitation?
I using the TPS25981 calculator to fill itimer to 800ms seems show some error.
Thanks!

Part Number: TPS25981 Tool/software: Experts,
QOD
Could you please help us list all the conditions to trigger the QOD MOSFET turn-on and discharge the output ?
Datasheet just lists one trigger condition: the VEN<VUVLO … however, our customer got some…
Hi Alberto,
Can you share the layout screenshot (all layers) or files. I only need to check the eFuse part of it. There might be some issue in the layout.
Can you add some external input capacitance and just check if it is helping? It should be a quick…
