LP8758-E0: I2C lines at 3.3V a problem with reliability?

Joey Yuen

Part Number: LP8758-E0

Hi Team,

Do we have any concerns if a customer wants to drive their I2C lines at 3.3V?

I know our recommended is 1.8V to support all I2C speeds, but if they only need 400kHz and drive at 3.3V, is there any concern?

Thanks!

    Hi Joey,

      We've re-characterized the digital I/O level, and will update the datasheet with the I/O level absolute maximum ratings to VANA+0.3V; recommend it to VANA+0.3V with 3.3V maximum. so, 400kHz at 3.3V has no problem at all.

    Thanks!
