    Abstract: Systems, methods, and apparatus managing access to a power management device are disclosed. A system has a primary integrated circuit and a power management integrated circuit. The primary integrated circuit has a communication controller configured to control access to a first serial bus for a plurality of subsystems in the primary integrated circuit. The power management integrated circuit is coupled to the first serial bus and to a second serial bus. An access control circuit in the power management integrated circuit is configured by the primary integrated circuit to control access to the power management integrated circuit through the second serial bus. The primary integrated circuit may be configured to write an access control configuration to the power management integrated circuit. The access control configuration may define write access rights for a secondary integrated circuit coupled to the power management integrated circuit through the second serial bus.

    Abstract: A circuit comprising an ECM system is provided. The circuit includes a current monitor circuit configured to monitor the ECM system to measure a set of currents supplied to a set of circuits. The circuit also includes an alert circuit configured to generate an alert based on at least one current of the set of currents in comparison to at least one threshold. The circuit further includes a throttle circuit configured to throttle a performance of at least one circuit in order to decrease the current to the at least one circuit based on the generation of the alert. The current used by the circuit may act as an analogue for the system power used. Accordingly, the current used by the circuit may be used to determine when to throttle one or more aspects of the functionality of the circuit.

    Abstract: Systems and methods are disclosed resetting a slave identification (SID) of an integrated circuit (IC). An exemplary method comprises determining that a plurality of ICs in communication with a shared bus have the same SID, the shared bus operating in a master/slave configuration. A common memory address of the ICs is identified, where data stored in the common memory address is different for a first IC and a second IC. Each of the ICs receives over the shared bus a new SID value and match data. The ICs compare the match data with the data stored in the common memory address. If the match data is the same as the data in the common memory address, the SID is changed the received new SID value.
