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,
