I have a question ADUM5242 Junction Temperature .
ADUM5242 has θJa typ 80C/W.
Do you have a θjc and Tj specs?
Or is it the correct way to calculate using Figure 4?
What is the calculation method at that time?
I use an iCoupler ADuM5242 in a device that is currently under test at UL.
Regarding the safety clearances, the UL inspector does not accept the CTI value of 175V described in the document. He says it was not tested under UL and so, he cannot accept…
The ADuM5242 input should not be left floating, this can cause it to sit at a level between the VOH and VOL levels and can give uncertain output results and draw some current at the input. Instead, connect with a large value resistor (1M ohm)…
Are there any low power alternatives to the ADuM5241/ADuM5242? The maximum quiescent current is over 100mA!
My requirement: 2.5kV isolation, 1.8V - 5.5V at 100uA output, lower input current draw, small package, single channel isolated feedback
