our  customer  is  using  the  ADUM6400. Now  there  where  some  PCNs , and 
some  specs. Are  getting  worthier  . What  can he do ?

1. Original Specification:

Reinforced insulation per CSA 60950-1-03, 600 V rms maximum working voltage

Actual specification:

Reinforced insulation per CSA 60950-1-07, 380 V rms maximum working voltage


They  need 400 Vrms  and  480Vrms (utility mains voltage).


2. Why  was  there  no PCN for  this ?

Is  there a  replacement  for  the ADUM6400 with 600 Vrms?

How  can they  use the  old  device  ,ADUM6400 , in their design  to meet  the 
specs?

 

1. The package creepage for W-SOIC-16 per CSA no longer supports reinforced at
600V rms. They could switch to the RI-16-1 package which has more creepage and
has VDE certificate.

2.

Why  was  there  no PCN for  this ? -> The certificate changes happened between
datasheets with the initial datasheet stating certifications “pending”. It was
due to a change made by CSA described above.

Is  there a  replacement  for  the ADUM6400 with 600 Vrms? -> We only have the
ADuM6400 with the RI-16-1 and certificate described above.
