is this part available in AEC-Q100 ?
ADuM4120 /1 系列可实现超低传播延迟，且不影响共模瞬变抗扰度 (CMTI) 性能。 ADuM4120 /1 可在高温范围和高工作电压下工作，非常适合改进太阳能逆变器、电机控制器和工业逆变器应用的能源效率和时序性能稳定性。
I am confused about the safety ratings of the part ADuM4120. Its datasheet states reinforced insulation for a working voltage of 400Vrms to meet IEC61010-1, while the rating for reinforced insulation with VDE0884-10 is 849Vpeak.
Thank you for your reply.
I was checking ADuM4210 datasheet.
Also I was checking ADuM4233 datasheet.
The schematic you have drawn is correct, and a possible implementation of driving GaN. I don't recommend using the ADuM3221, though, for a few reasons:
1) The CMTI is only 25 kV/µs, and GaN usually switches at a very fast slew rate
Thank you RSchnell,
My mistake R2 connection, the idea was to put R2 in series to gate´s.to see SR control.
I see, ADuM4120 seem a better option.
ADUM4120 VDD2 has been tested in 250mA and 1A.
we are evaluating this P/N, for 2A+ current ability, and Switching Frequency 200Khz. Solar PV application.
Could you tell me the power supply for VDD2 of ADUM4120 recommended value? 250mA?
we use 16pcs…
The ADuM3123 is capable of operating at 6.78 MHz, but there will be significant self heating within the IC. The ADuM3123 also has a minimum pulse width of 50 ns, so if the design requires pulses shorter than that, there may be an issue.
