摘要： A driving circuit has output terminal connected to an ultrasonic transducer and provides an output voltage. The driving circuit includes an output transistor coupled between a voltage reference and the output terminal, a high voltage comparator coupled to said output terminal and to a threshold voltage reference), a start-up circuit controlled by a setting signal; and a switching ON/OFF circuit having an input coupled to the start-up circuit an input coupled to the comparator, and an output coupled to a control terminal of the output transistor. The start-up circuit provides an ON signal to the switching on/off circuit and the comparator provides an OFF signal to the switching on/off circuit which switches off the output transistor. The high voltage comparator generates the switching off signal in response to the output voltage reaching a desired supply voltage value which depends on the value of the first threshold voltage reference.

摘要： In an integrated pressure sensor with a high full-scale value, a monolithic body of semiconductor material has a first and a second main surface, opposite and separated by a substantially uniform distance. The monolithic body has a bulk region, having a sensitive portion next to the first main surface, upon which pressure acts. A first piezoresistive detection element is integrated in the sensitive portion and has a variable resistance as a function of the pressure. The bulk region is a solid and compact region and has a thickness substantially equal to the distance.
