Hi,
my customer is connecting INA and INB of UCC27524 together, and they are driving 2 IGBT's in parallel.
They wonder which scheme is better:
1. Connect OUTA and OUTB together at the device side and route one wire to 2 IGBT's gate side.
2. Connect OUTA to IGBT 1's gate side, Connect OUTB to IGBT 2's gate side.
Which is better? Or do you have better suggestion?
And in the related post, it's said
The UCC27424 is better suited for connecting directly in parallel due to the bipolar/FET output structure, and the switching times are a little slower.
Why bipolar output structure is better suited for parallel connecting?
