Patent number: 10483213Abstract: Many integrated circuit die are fabricated on a wafer. Each die includes integrated functional circuitry with an array of fuse elements that are visible to optical inspection. An electrical wafer sort is performed to test the integrated functional circuitry of each die. The array of fuse elements for each die on the wafer are programmed through the electrical wafer sort process with data bits defining a die identification that specifies a location of the die on the wafer. The die is then encapsulated in a package. In the event of package failure, a decapsulation is performed to access the die. Optical inspection of the array of fuse elements is then made to extract the die identification.Type: GrantFiled: September 13, 2017Date of Patent: November 19, 2019Assignee: STMicroelectronics S.r.l.Inventors: Giona Fucili, Agostino Mirabelli, Lorenzo Papillo

Patent number: 10303193Abstract: A dual-input, single-output low-dropout voltage regulator circuit includes: a first supply terminal, a second supply terminal and an output terminal, and first and second transistors having current paths coupled respectively between the first and second terminal and the output terminal. First and second drive circuit blocks are coupled respectively to the first and second supply terminals and drive the control terminals of the first and second transistors to provide a regulated voltage at the output terminal from the voltage on the first supply terminal and the second supply terminal. An input circuit block is sensitive to the voltage at the output terminal and is coupled to the first and second drive circuit blocks and configured to activate the second transistor to provide regulated voltage at the output terminal from the second terminal as a result of the voltage at the output terminal becoming lower than a desired value.Type: GrantFiled: March 22, 2018Date of Patent: May 28, 2019Assignee: STMicroelectronics S.r.l.Inventors: Marco Sautto, Davide Betta, Agostino Mirabelli

Patent number: 9362855Abstract: An embodiment of a motor controller includes first and second supply nodes, a motor-coil node, an isolator, a motor driver, and a motor position signal generator. The isolator is coupled between the first and second supply nodes, and the motor driver is coupled to the second supply node and to the motor-coil node. The motor position signal generator is coupled to the isolator and is operable to generate, in response to the isolator, a motor-position signal that is related to a position of a motor having at least one coil coupled to the motor-coil node. By generating the motor-position signal in response to the isolator, the motor controller or another circuit may determine the at-rest or low-speed position of a motor without using an external coil-current-sense circuit.Type: GrantFiled: April 8, 2014Date of Patent: June 7, 2016Assignees: STMICROELECTRONICS, INC., STMICROELECTRONICS S.R.L.Inventors: Frederic Bonvin, Agostino Mirabelli, Maurizio Nessi

Patent number: 8704479Abstract: A system and method for determining the start position of a motor. According to an embodiment, a voltage pulse signal may be generated across a pair of windings in a motor. A current response signal will be generated and based upon the position of the motor, the response signal will be greater in one pulse signal polarity as opposed to an opposite pulse signal polarity. The response signal may be compared for s specific duration of time or until a specific integration threshold has been reached. Further, the response signal may be converted into a digital signal such that a sigma-delta circuit may smooth out glitches more easily. In this manner, the position of the motor may be determined to within 60 electrical degrees during a startup.Type: GrantFiled: November 8, 2010Date of Patent: April 22, 2014Assignees: STMicroelectronics, Inc., STMicroelectronics S.r.l.Inventors: Frederic Bonvin, Davide Betta, Agostino Mirabelli, Andrea Di Ruzza

Patent number: 8471505Abstract: A device for the change of the driving mode of an electromagnetic load from a first operating mode with pulse width modulation to a second operating mode that is linear by means of switching circuits. During a first operating mode, each of two outputs has a voltage value ranging from a first reference voltage to a second reference voltage. The device adapted to synchronize a change command signal from a first operating mode to a second operating mode of the electromagnetic load with the signal representative of the flow of current circulating within the load at substantially its average value and adapted to generate a first command signal in response to the synchronization.Type: GrantFiled: March 31, 2010Date of Patent: June 25, 2013Assignee: STMicroelectronics S.r.l.Inventors: Ezio Galbiati, Roberto Peritore, Michele Bartolini, Agostino Mirabelli
