I have some question for Peak Current of UCC27517A-Q1.
Q1.
The absolute maximum of the datasheet includes "peak 4A at 0.5us" and a mention. (p3 Absolute maximumu ratings)
Is there any problem in the case of less than 40ns of 7A Peak?
I cannot increase gate resistance. Because switching loss becomes big.
Q2.
There are "+-4A at Cloda=0.22uF, Fsw=1kHz" mention in lsrc/snk of the datasheet.
Does the gate resistance use several Ω then?
Q3.
Datasheet shows the current as +/-4A typ.
How does device limit the current under 12V Vcc condition?
If internal resistance is 1ohm, I guess output current achieve around 12A at turn on the output. However datasheet shows +/-4A. I don’t know why?
