[SI-LIST] Re: Analysis about hot-plug

Zhangkun, it is not a trivial problem.  It is affected by the 
architecture of the power front end, power converters, and the 
reflected impedance of the load.  Many variations are possible.

Your capacitor charge time difference is the result of a hard current 
limit circuit.
