UCC5390-Q1: 12V VCC1 considerations?

Part Number: UCC5390-Q1

Curves in the datasheet are mostly for 3.3V or 5V VCC1. As a critical component, are there any considerations, tradeoffs to using 12V? Will propagation delay be affected?

Thanks

  • Hi, Stephanie,

    After the logic inputs, there is an LDO and some level shifting going on, so the impact on performance due to VCC1 level is not significant.

    Remember, if you run VCC1 from 12V, your logic thresholds will be a percentage of that. See this FAQ for more info.

    Let me know if you have further questions, else mash the Green Button so I can get my cookie!
