US Patent:

20100308780, Dec 9, 2010

Filed:

Jun 8, 2009

Appl. No.:

12/480392

Inventors:

Weiguang Qiu - Fremont CA, US
Robert Gee - Sunnyvale CA, US

Assignee:

VISHAY INFRARED COMPONENTS, INC. - Santa Clara CA

International Classification:

H02J 3/12

US Classification:

323237

Abstract:

An electronic component for providing optical isolation an electronic component package, a phototriac disposed within the electronic component package for providing the optical isolation, and a reverse zero-cross feedback channel integrated into the electronic component package to thereby provide zero-cross detection. The electronic component may be in a circuit which includes a phase control circuit. A method of driving an AC load and providing zero-cross detection using a single electronic component includes providing an electronic component having an electronic component package, a phototriac disposed within the electronic component package, and a reverse zero-cross feedback channel integrated into the electronic component package to thereby provide for zero-cross detection. The method further includes placing the electronic component within a circuit.

Robert GEE - Sunnyvale CA, US

Assignee:

Maxim Integrated Products, Inc. - San Jose CA

International Classification:

G01R 31/28
G01R 31/317

Abstract:

Circuitry, systems, and methods for fault detection and reporting comprise a fault detection circuit configured to detect one or more fault conditions that cause a state change in a fault pin voltage representative of a transceiver failure. Once the state of the fault pin voltage changes, a transceiver input generates a fault detection code. In embodiments, in response to the transceiver input receiving a first signal, the fault detection code is shifted to a transceiver output that may communicate the fault detection code to a controller. Once the transceiver input receives a second signal, the fault pin voltage may be reset to clear the fault detection code before resuming operations, including detecting additional fault conditions as they arise.
