I don't know for sure. If you want clean and EMI tolerant gate drive I like totem pole drive, located close to the MOSFETS.
I would seriously consider the TLP350 and other opto coupled driver ICs such as the FOD3182 These seem to be fast enough and can drive a couple of Amps. What is best is there is zero crosstalk from the input pins to and from the output drive pins. You can physically locate the IC within 10mm of the FETS so the lead lengths can be short as can be.
You will need a small isolated 15V supply for each high side and one for the two low sides of the bridge.
The TLP350 and Fod3182 specs show a totem pole output stage so you are getting that, just not from discrete components.
The Recom RE1215S dc/dc converters are cheap and easy to use. Cost about $12 each. Saves me a heap of time and farting about with Aliexpress cheapies. |
