Find files to check ADuM7441 reliability - test isolation.

Hi:

Could you please share more about how customer perform the isolation test?

ADuM744x is proof tested according to UL1577. Before the test,pins on side 1 and side2 are tied together separately. Then 1200Vrms insulation voltage is applied across isolation barrier for 1 sec. leakage current is monitored and threshold is 5uA.

Hi Chris.
Thank you very much for your answer.

The customer tested the ADuM7441 with an average insulation voltage of 1000 V for one minute. Could you give a link to UL1577?
