Table_3._PMBus_Command_Code_Coefficients
The host system uses the following equation to convert
the value received from the PMBus device—in this case,
the MAX34441—into a reading of volts, degrees Celsius,
or other units as appropriate:
where X is the calculated, real world value in the appro-
priate units (V, NC, etc.); m is the slope coefficient; Y is
the 2-byte, two’s complement integer received from the
PMBus device; b is the offset; and R is the exponent.

To send a value, the host must use the below equation
to solve for Y:
where Y is the 2-byte, two’s complement integer to be
sent to the unit; m is the slope coefficient; X is the real
world value, in units such as volts, to be converted for
transmission; b is the offset; and R is the exponent.
