Hi,
Our customer wants clarification about the compatibility of the MC34VR5100A2EP PMIC with the LX2160A PMBus. Specifically, their question is the following:
Will the NXP PMBus driver work with this? Can the slope (m) be changed to a different value based on Read or Write.
Using Direct Mode
VOUT_COMMAND
R=0
m=500
b=0
READ_VOUT
R=0
m=800
b=0
For VOUT_COMMAND
For READ_VOUT
Thank you
Hi, there was a misunderstanding with this request. Please see clarification from the customer below:
"
My question is in regards to the LX2160A PMBus driver capabilities when using PMBus Direct VOUT_MODE.
I'm looking to see how the driver deals with the coefficients, m, b & R. Are they fixed during set up or can they be changed on the fly? I want to verify the selected power supply is compatible.
Attached is a page from the PMBus Protocol Spec. I haven't found anything in the NXP documentation that explains the PMBs operation.
Also, this from the LX2160A datasheet
How does the value stored in the Fuse Status Register get configured to a format usable by a PMBus device and get transferred?

Kind regards,
Unfortunately for the LX2160A part questions you need submit ticket to LX2160A support team.
Here only support the PMIC side questions.
Do you mean the DVS speed selection for SWx of VR5100?
If yes,it can be changed by setting as below picture:
