Patent number: 12092689Abstract: A Scan test in a single-wire bus circuit is described in the present disclosure. The single-wire bus circuit has only one external pin for connecting to a single-wire bus. Given that multiple physical pins are required to carry out the Scan test, the single-wire bus circuit must provide additional pins required by the Scan test. In embodiments disclosed herein, the single-wire bus circuit includes a communication circuit under test, and a driver circuit coupled to the communication circuit via multiple internal pins. The driver circuit uses a subset of the internal pins as input pins and another subset of the internal pins as output pins to carry out the Scan test in the communication circuit. As a result, it is possible to perform the Scan test without adding additional external pins to the single-wire bus circuit, thus helping to reduce complexity and footprint of the single-wire bus circuit.Type: GrantFiled: December 8, 2021Date of Patent: September 17, 2024Assignee: Qorvo US, Inc.Inventors: Alexander Wayne Hietala, Christopher Truong Ngo, Ryan Lee Bunch

Patent number: 10365317Abstract: A semiconductor element test apparatus includes a first switch having a switching element, a coil, a second switch, a semiconductor element, a first rectifying element, and a second rectifying element. The first switch, the coil, and the second switch are connected in series to a power source. The semiconductor element is disposed to configure a loop path along with the coil and the second switch when the switching element is switched off. The semiconductor element has a diode element. A cathode electrode of the diode element is connected to a positive electrode of the power source. The second rectifying element is connected to the first rectifying element in series, and has a rectification direction opposite to a rectification direction of the first rectifying element. The first rectifying element and the second rectifying element configure, along with the coil, another loop path which is different from the loop path.Type: GrantFiled: June 9, 2016Date of Patent: July 30, 2019Assignee: DENSO CORPORATIONInventors: Masanori Miyata, Yoshifumi Okabe
