Part Number: ISO5451-Q1
Comparison test is carried out in the same machine, with the same load, the difference lies in the drive scheme, driven by EXB841 (15KHZ), the test on the heat sink temperature is about 80 degrees, if replaced by ISO5451, even if the switching frequency is reduced to 10KHZ (IGBT helps to reduce the heat sink). The temperature reached 90 degrees.
I have the following advice on the application1,How much ISO5451 can drive current of IGBT, whether or not the expansion of the transistor?2, whether the application of the "2A active Miller clamp" function?
3.Why ISO5451 drive IGBT will be high
ISO5451 drive IGBT, RG with a 5.62 ohm resistor, this is the drive waveformer than EXB841 .
and My circuit is the same as the IC TI picture 43
