Original question:

DP83TG720R-Q1: Go in Sleep Mode

DP83TG720S-Q1: power management module for sleep mode

Part Number: DP83TG720S-Q1
Other Parts Discussed in Thread: LM3880, TPS22993

Hi Team,

Can you suggest a power management module that would allow the user to enter/exit the sleep mode feature of the phy ethernet DP83TG720S-Q1? 

Can you confirm the combination of a sequencer (LM3880) and a load switch (TPS22993) would work? if not can you suggest other devices? if possible a single IC solution?

Thank you kindly.

Regards,

Marvin

    Hi Marvin,

    Just to be clear, DP83TG720S does not support standard based sleep entry and exit. It is a custom solution and may only work between 720-720.

    But if customer wants to evaluate it further, they can follow the implementation as per diagram : 7-12 of datasheet. Any PMIC with enable signal and required current output ratings should work.
