Device, method and system to indicate an amount of a load current provided by power supply units

A system comprising:

• multiple power supply units (PSUs) coupled to each other via a bus;
• first circuitry coupled to each of the multiple PSUs via the bus, the first circuitry to receive a first signal from a designated primary PSU on the bus, wherein a first voltage level of the first signal is to indicate a target amount of current to be output by each of one or more PSUs of the multiple PSUs;
• and
• second circuitry coupled to the first circuitry, the second circuitry to:
• receive one or more second signals which are to indicate, for each power supply unit of the multiple PSUs, whether the power supply unit is to participate in a delivery of power to a load;
• determine, based on the one or more second signals, a total number of the one or more PSUs;
• and
• provide to the first circuitry one or more third signals which indicate a scale factor based on the total number;
• wherein the first circuitry is further to generate a fourth signal based on the first signal, comprising the first circuitry to perform an amplification based on the scale factor;
• and
• a display device coupled to the multiple PSUs, the display device to display an image based on a signal communicated with the load.

A device comprising:

• first circuitry to:
• receive a first signal from a current share bus that is coupled to each of multiple power supply units (PSUs) including a designated primary PSU, wherein a first voltage level of the first signal, which is from the primary PSU, is to indicate a target amount of current to be output by each of one or more PSUs of the multiple PSUs;
• generate a second signal based on the first signal, and on one or more third signals which indicate that the primary power supply unit (PSU) of the multiple PSUs is a source of the first signal;
• second circuitry to:
• receive one or more fourth signals which are to indicate, for each PSU of the multiple PSUs, whether the PSU is to participate in a delivery of power to a load;
• generate, based on the one or more fourth signals, one or more fifth signals which indicate a total number of the one or more PSUs;
• and
• third circuitry, coupled to the first circuitry and the second circuitry, to generate a sixth signal by performing an amplification with the second signal based on the one or more fifth signals.
