Q
Is it possible to use ADuM1400 in IGBT transistors gate control in asynchronousinduction motor control circuit? Will the ADuM have tolerance to EMI?
A
The ADuM1400 can indeed be used from an EMI point of view. I think thecustomer would…
Hi
A customer asks me about the ADuM3400.
The ADuM3400 is said to have better ESD immunity in the system than the ADuM1400.
(By ADuM3400 Datasheet & AN-793)
In the link below, there is no problem with 8kV for contact discharge and 15kV for air discharge…
Hi, I have found a strange behaviour in the ADUM1400BRWZ: the datasheet says the pin 7 shouldn't be connected but if I don't connect it the inputs are disabled. Then I tried to connect pin 7 first to GND1 and then change it to VDD1 to see the diferences…
Hi
I am considering latchup with the ADuM1400.
There is a description about latch-up trigger current in AN-793,
and there is a description to limit the current to 25mA or less that is lower than this value.
How much is the latch-up trigger current in the…
Hello ADI Support:
My customer is currently designing an isolated serial card using the ADUM 5400. The PCB dimensions will be the standard PC-104 card size. Along with the ADUM 5400, They will also be using the ADUM1400 to isolate other signal lines…
Hi,
Our customer made a question about ADuM1400 in their prototype board, which VDD2 is unpowered a little while(maybe around 10ms) during power regulator starting-up to 3.3V triggered by a power switch, against 5V VDD1 is always powered, however there…
Hallo,
can you say me are correct placed on the board? The distance between elements is measured 4mm. We will use FR4 material for PCB(1.2mm 4 Layers).
Thanks
