- 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.

+title: Infineon XDP720 / XDP730 Digital eFuse Controllers

+maintainers:

+
+description: |
+ The XDP720 and XDP730 are PMBus-compliant digital eFuse controllers
+ with an integrated current sensor. They provide accurate system
+ telemetry (V, I, P, T) and report analog current at the IMON pin for
+ post-processing.
+
+ 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).
