- The XDP720 is an eFuse with integrated current sensor and digital
- controller. It provides accurate system telemetry (V, I, P, T) and
- reports analog current at the IMON pin for post-processing.

- Datasheet:

+ Both parts share the same PMBus register map and direct-format
+ coefficients; they differ in the GIMON gain step exposed via the
+ TELEMETRY_AVG register (bit 10) and in the VDD_VIN pin number
+ (XDP720: pin 9, XDP730: pin 20).
