The Input ESD structures of the ADuM120N and ADuM121N will look like this:
And the output will look like this:
You could try ADuM120N or ADuM121N. The power up glitch is resolved in design level.
For ADuM128x, we did not see this glitch on bench evaluation, if you really want it, we can double confirm with designer. please send mail to me via chris.qin…
IDD1 = IDD1(Q) + (2.8mA * D_A + 0.01mA/Mbps * F_A) + (2.8mA * D_B + 0.01mA/Mbps * F_B)
IDD2 = IDD2(Q) + (0.02mA/Mbps * F_A)+ (0.02mA/Mbps * F_B)
IDD1 = IDD1(Q) + (2.8mA * D_B + 0.01mA/Mbps * F_B) +(0.02mA/Mbps * F_A…
The ADuM3211 is an edge encoding architecture. The isolator sends either a single or double pulse when the input detects a state transition. If the input does not detect a change within ~1us, it will send a refresh pulse. The refresh is for…
