Tool/software:

Hi support team,

Looking at SLVSGD5, it says that the LP5890 has an "intelligent power saving mode."

The LP5890 does not have MPSM commands like the LP5891.
Does the LP5890 really have an "intelligent power saving mode"?

According to the following thread, it does not seem to have this mode.

Hi Dice-K,

LP5890 just supports basic power save mode which can be enabled in the FC0 with BIT PSM_EN and just LP5891 not only support basic power save mode but also support intelligent power save mode with lower ICC.

Hi Monet,
Thank you for your reply.

I think it would be better to remove the word "Intelligent" from the LP5890 to avoid confusion.

Best regards,
