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

Forget about simulating the electrical on your capacitors, simulating =
how your pins mechanically engage or bounce around will be challenging =

Zhangkun, it is not a trivial problem.  It is affected by the=20
architecture of the power front end, power converters, and the=20
reflected impedance of the load.  Many variations are possible.

Your capacitor charge time difference is the result of a hard current=20
limit circuit.
