TH54110B - Operating a bus with an integrated circuit in a de-energized state - Google Patents

Abstract

The circuit layout can be used for various systems. For example, consumer electronic devices make communication between components such as various integrated circuits, in contact with the bus, as illustrated in its shape.The RUN power supply is adjusted to the closed state in response to abnormal conditions. That together with a common circuit connected to the bus Controls the load on the bus generated by the interface circuit. And integrated circuits, so that communication between devices on the bus can be continued so that even when abnormal conditions are Resulting in loss If the RUN power supply is lost, the command can be transmitted through the bus from the first integrated circuit in the state With energy to The second integrated circuit is in the energized state while the third integrated circuit contacts the bus. In a non-powered state

Claims (1)

1.The circuit layout consists of a bus connected to the first power supply, the first integrated circuit connected to the bus, the second integrated circuit connected to the bus, and the third integrated circuit connected to the bus through a circuit interface circuit. Combine the third and the interface circuit. Each of them is connected to the first and second RUN power supplies, respectively, on the RUN power supply loss, the load-controlled interphase circuit on the bus. By inter-phase circuit and third integrated circuit in such a way that it can make the loop
