Abstract: A disclosed method for restoring bus functionality includes detecting, by an automatic bus recovery block, that at least one target device on a bus pulls at least one line of the bus to a low level. The method also includes initiating, by the automatic bus recovery block, a timer to time a duration of the low level of the line. Additionally, the method includes detecting, by the automatic bus recovery block, that the duration of the low level of the line exceeds a predetermined time limit. Furthermore, the method includes alerting, by the automatic bus recovery block, a controller device on the bus that the duration of the low level exceeds the predetermined time limit to reset the line of the bus to a high level. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: A method for operating a system including a voltage regulating power supply includes sensing a local voltage on a first node of the system and a remote voltage on a second node of the system. The first node and the second node are in a conductive path coupled to a load of the system. The first node is closer to a power stage of the voltage regulating power supply than the second node. The second node is closer to the load than the first node. The method includes detecting a load release event based on the local voltage, the remote voltage, and at least one predetermined threshold value.
