title: Infineon XDP720 / XDP730 Digital eFuse Controllers

maintainers:
  - Ashish Yadav <ashish.yadav@infineon.com>

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).

    description:
      The value of the RIMON resistor, in micro ohms, required to enable
      the system overcurrent protection.

  vdd-vin-supply:
    description:
      Supply for the VDD_VIN pin (XDP720 pin 9, XDP730 pin 20), the IC
      controller power supply.  Typically connected to the input bus
      (VIN) through a 100 ohm / 100 nF RC filter.
