Hi experts,
We choose this ADM1278 hot-swap controller. I use HotSwapDesigner to calculate Rsense 0.3mohm for 293 A threshold. Would you advise what the timing can handle if a system could run surge current 253A , 200us. I read the datasheet, but don't which it's the timing.

1. Should I refer to POR duration 27ms? What are POR duration, Glitch Filter, and Pull up/down current meaning?

2. There is a register for overcurrent. Is it for timing and can it be changed?

Appendix:
Just double check the overcurrent protection is for 293A with Rsense 0.3mohm?

Many thanks!
