Hi team,

I have one question on TPS4800-Q1.

The FLT_GD is described as UVLO of gate drive, why it is asserted when PU to SRC is above 7.5V, instead of below 7.5V?

Hi Xiaoying,

Generally fault outputs (FLT_bar) are pulled LOW when fault happens. In this case, we term it as FLT_GD without bar. So, it is asserted LOW when PU to SRC voltage is GOOD.
