Dear support member,

My customer is considering MP4245.

There is question about Registers “Line Drop Compensation Gain” and “MFR_STATUS_MASK”.

Q1.
Line Drop Compensation Gain: 0.
Even if the line drop compensation is “0” (= no compensation),
Does this satisfied with the USB-PD standard?

Q2-1.
Even if VOUT MASK is “Mask”,
Does this satisfied with the USB-PD standard?

Q2-2.
If VOUT MASK is “Not Mask” case.
When does the ALT pin work when Not Mask (default)?

Q3-1.
Even if PG_STATUS_MASK and PG_ALT_EDGE_MASK is “MASK”,
Does this satisfied with the USB-PD standard?

Q3-2.
Does it mean that the ALT pin does not work in the PG state when PG_STATUS_MASK is MASK?

Q3-3.
Does PG_ALT_EDGE_MASK work regardless of the PG_STATUS_MASK setting?

Q4-1.
Even if Other MASK and Unknown MASK is “MASK”,
Does this satisfied with the USB-PD standard?

Q4-2.
If Other MASK and Unknown MASK is “Not Mask” case.
When does the ALT pin work when Not Mask (default)?

Best regard.
