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.

Transmitting apparatus of digital signals on a supply line of electronic devices and corresponding method

An electronic synchronous/asynchronous transceiver device for power line communication networks is integrated into a single chip and operates from a single supply voltage. The transceiver device includes: at least an internal register that is programmable through a synchronous serial interface; at least a line driver for a two-way network communication over power lines implemented by a single ended power amplifier with direct accessible input and output lines that is part of a tunable active filter for the transmission path; and at least a couple of linear regulators for powering with different voltage levels different kind of external controllers linked to the transceiver device.

A data transceiving station of digital data frames includes a digital modem coupled to a transmission line, and a microprocessor receiving demodulated data from the modem according to a Packet Mode or a Bit Mode transmission through an interface circuit. The interface circuit switches between the Packet Mode and the Bit Mode transmission during transfer of a data frame to the microprocessor. The data transceiving station combines the superior speed of a Packet Mode transfer with the unlimited compatibility of a Bit Mode transfer.

Multichannel transceiver of digital signals over power lines

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.

System of management of the trimming of integrated fuses within a scan test architecture

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.
