Patent number: 11264982Abstract: A high voltage driving circuit for driving a load receives a low voltage input signal and generates a high voltage output signal. A short circuit protection circuit including a first electronic switch operated by the low voltage input signal and a second electronic switch operated by a low voltage signal obtained by a voltage division of the output high voltage signal. The first electronic switch causing a first pull-up current to be sent to a capacitive element whose voltage controls an input of a threshold comparator. A second electronic switch causes a second pull-down current to be drawn from the capacitive element whose voltage controls the input of the threshold comparator. A short circuit detection signal is generated at an output of said threshold comparator, indicating a short circuit and capable of inhibiting operation of the driving circuit.Type: GrantFiled: April 3, 2018Date of Patent: March 1, 2022Assignee: STMicroelectronics S.r.l.Inventors: Marco Terenzi, Davide Ugo Ghisu

Patent number: 10211826Abstract: A high-voltage electronic switch includes first and second transistors defining a current flow path between an input and output of the switch. The transistors have a common point of the current flow path and a common control terminal. A control circuit includes a voltage line receiving a limit operating voltage and first and second branches coupled between the voltage line and the common point and common control terminal, respectively. Further transistors are activated, upon turning-off of the first and second transistors, for coupling the branches to the voltage line. The branches include a parallel connected resistor, diode, and string of diodes with opposite polarities. The diode of the first branch plus string of diodes of the second branch and diode of the second branch plus string of diodes of the first branch provide coupling paths between the voltage line and, respectively, the common point and common control terminal.Type: GrantFiled: April 5, 2018Date of Patent: February 19, 2019Assignee: STMicroelectronics S.r.l.Inventors: Marco Terenzi, Davide Ugo Ghisu
