Abstract: A circuit may include an audio amplifier (314) configured to amplify an input signal (SAUDIO) to generate an output signal (SOUT+, SOUT−) suitable for driving a loud speaker (316). A first circuit (318) may be configured to generate a first analog signal (SI) based on a current level drawn by the loud speaker (316), and a second circuit (320) may be configured to generate a second analog signal (SV) based on a voltage supplied across the loud speaker (316). A third circuit (322, 312) may be configured to generate a third analog signal (RESIDUE) based on the difference between the first and second analog signals, and modify the input signal (SAUDIO) based on the third analog signal.

Abstract: An embodiment driver circuit comprises a power supply pin configured to receive a power supply voltage, and a set of control pins configured to provide a set of control signals for controlling switching of a set of switches of an h-bridge circuit comprising a pair of high-side switches and a pair of low-side switches. The driver circuit comprises control circuitry coupled to the control pins and configured to generate the control signals, and sensing circuitry coupled to the power supply pin and configured to generate a detection signal indicative of the power supply voltage exceeding a threshold value. The control circuitry is sensitive to the detection signal and is configured to generate the control signals to activate one of the pair of high-side switches and the pair of low-side switches and de-activate the other of the pair of high-side switches and the pair of low-side switches.

Abstract: In a non-volatile memory device, a memory sector is provided. The memory sector includes a plurality of tiles arranged horizontally. Each tile includes a plurality of memory cells arranged in horizontal word lines and vertical bit lines. A pre-decoder is configured to receive a set of encoded address signals to produce pre-decoding signals. A central row decoder is arranged in line with the plurality of tiles, receives the pre-decoding signals and produces level-shifted pull-up and pull-down driving signals for driving the word lines. First buffer circuits are arranged on a first side of each tile. Each of the first buffer circuits is coupled to a respective word line, receives a level-shifted pull-up driving signal and a level-shifted pull-down driving signal, and selectively pulls up or pulls down the respective word line as a function of the values of the received signals.

Abstract: The present disclosure relates to a method for booting a processing device, the method including: generating, by a monotonic counter and during a first boot phase, a first count value; transmitting, by the monotonic counter, the first count value to an access control circuit of a memory; reading, on the basis of the first count value, first data stored in the memory; and generating, by the monotonic counter and during a second boot phase, a second count value greater than the first count value. The access control circuit of the memory is configured so that the reading of the first data is not authorized on the basis of the second count value.
