Abstract: An embodiment method of detecting an arc fault includes communicating a power line signal, including a communication signal modulated on an alternating current power signal, over a power line. The communication signal is communicated according to a power line network protocol. A power spectrum of the communication signal includes a first frequency band and a second frequency band different from the first frequency band. In accordance with the power line network protocol, a power of the communication signal in the first frequency band is attenuated in comparison to the power of the communication signal in the second frequency band. The method further includes performing arc fault detection on the spectral portions of the power line signal that are within the first frequency band.

Abstract: Functions for simulating, burning and controlling integrated fuses of a device are provided by a dedicated circuit which, instead of differing from other circuits, is integrated by sharing part of the registers with the circuit that normally exists to scan test the integrity of the state of the device. The architecture is simplified and only requires an additional pin as compared to a common scan test circuit.

Abstract: A method for controlling the level of a signal produced by a transceiver of digital data coupled to a power distribution line during a transmission phase is provided. The level of the signal output by the transceiver is regulated by comparing the current level of the output signal with a predetermined minimum threshold and a predetermined maximum threshold, reducing the current level when the maximum threshold is exceeded by reducing the gain, and switching to a voltage mode control of the output signal when the current level of the output signal becomes lower than the minimum threshold.
