ISO5852S: What does ISO5852S Split Outputs to Provide 2.5-A Peak Source and 5-A Peak Sink Currents

Part Number: ISO5852S
Other Parts Discussed in Thread: UCC256302

Hi All,

I used ISO5852 as IGBT driver for PMSM. In the datasheet, it said: "Split Outputs to Provide 2.5-A Peak Source and 5-A Peak Sink Currents". Does it mean each ISO8252 need provide 2.5-A peak source and 5-A peak sink currents to each IGBT. If I used 24VDC power to provide to ISO5852, and I have 6 ISO5852s and 6 IGBTs, I need prepare 6x5=30A maximum for 3 phase PMSM. If I use UCC256302 to generate 24VDC power for the driver and IGBT, the output current Iout = 30A for maximum. Is my calculation for the current for my driver to IGBTs correct? Or can you let me know the different calculation for the current of driver for IGBTs?

Best,

Hao
