UCD3138PSFBEVM-027: UCD3138PSFBEVM-027

Part Number: UCD3138PSFBEVM-027
Other Parts Discussed in Thread: UCD3138, LM7480-Q1, TPS2411, LM7480

Hello,

I wanted to know

1. The exact use of TPS2411PW in the schematic. It is used for oring purpose but I wanted to know can we implement oring with UCD3138 directly without using another controller in between. 

2. Since I need to implement for higher voltage rating (48V) so one similar controller that can be used is LM7480-Q1. Can you help me out with its implementation and replacement of old controller (TPS2411PW) as the

logic looks different and need an experienced person to help me out with this part.

Thanks and Regards.
