I was reading ADuM4120 datasheet.
But there was no specification for frequency.
How fast can ADuM4120 move?
For example, at ADuM3223/4223 datasheet, it says maximum frequency is 1MHz.
Unfortunately, the ADuM4120 can't source or sink very much DC current.
The ADuM4120 was designed for short durations of output current. If a constant current is pulled through the internal FETs, there is a lot of self heating that will occur…
is this part available in AEC-Q100 ?
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…
I was checking ADuM4210 datasheet.
Also I was checking ADuM4233 datasheet.
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.
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.
