摘要： A device for driving a power supply start-up circuit (10) for equipment fed with a power supply signal (VL) over a power supply line, includes: - a logic unit (14) for storing the operating state of the associated equipment, the logic unit (14) being activatable (VLU) by a start-up signal (VSTUP) over a start-up line reaching a start-up threshold, - a detector (20) coupled to the start-up line, wherein the detector (20) provides to the logic unit (14) a signal indicating a drop in the signal over the start-up line below a drop threshold, so that the detector (20) enables the logic unit (14) to continue operating in the presence of a failure of the power supply signal (VL) to store the operating state of said equipment upon occurrence of a failure in the power supply signal, and - a start-up circuit (22) sensitive to the power supply signal (VL). The start-up circuit (22) is activatable by the power supply signal (VL) as restored after a failure, in order to provide the start-up signal (VSTUP) able to reach the start-up threshold upon said power supply signal (VL) being restored. The device may prevent undesired default to an inactive condition of the associated equipment to an inactive, zero consumption state when power supply is restored after a failure.

摘要： A circuit (6) configured to debounce signals ( IN1 , IN2 ) produced by a quadrature encoder is disclosed. A first input node is configured to receive a first input signal ( IN1 ) and a second input node is configured to receive a second input signal ( IN2 ). The first input signal and the second input signal are in phase quadrature. An edge detector circuit (60) is configured to sense the first input signal and produce a pulsed signal ( E ) indicative of edges detected in the first input signal. A pulse skip and reset circuit (62) is configured to sense the pulsed signal and the second input signal, and produce a reset signal ( CLR ) indicative of pulses detected in the pulsed signal while the second input signal is de-asserted. A sampling circuit (64) is configured to sense the second input signal and the reset signal, and produce an output signal ( IN2 ') by de-asserting the output signal in response to assertion of the second input signal and asserting the output signal in response to a pulse being detected in the reset signal.
