Part Number: TPS4811-Q1 Tool/software: Hi team
we are using the TPS48110-Q1 in our new board ,i noticed that the equation for calculate Riscp :
is not correct (or i just missed something ):
i want that this driver will protect over current at…
Part Number: TPS4811-Q1 Tool/software: Hi Team,
I'm using TPS48110-Q1 for new electronic board.
This electrronic board must support the UL certification according to UL 60730.
For p/n TPS48110-Q1 , UL asks:
Pin FMEA Analysis for Pin Short…
Hi Syed,
Yes. This was a part of my original recommendations. Please follow these steps:
Sarah Raines said: It seems you may be using the incorrect RISCP equation. Please be aware that the TPS4811 datasheet has some sections incorrectly copied from…

Part Number: TPS4811-Q1 Tool/software: Hi team - We noticed that the TI evaluation board for this IC protects VS against negative voltages with a diode, but CS+, CS- and ISCP are not protected.
We have tried connecting ISCP to VS that is fed with a…
Hi Jimmy,
The schematic looks great! Please see the following recommendations:
-CBST is too small as of now. Please use the max total gate charge (worst case scenario) for the calculations (all FETs + pre-charge FET). A sufficient BST capacitor size…
