Patent number: 9000702Abstract: A packaged device includes a first die, a second die, and specially spaced and positioned sets of package terminals. The first die includes a pulse-width modulator (PWM), a processor, a timer, high-side drivers, low-side drivers, and a fault protection circuit. The second die includes ultra-high voltage high-side drivers. In an ultra-high voltage application, the PWM and external circuitry together form a switching power supply that generates a high voltage. The high voltage powers external high-side transistors. The processor and timer control the ultra-high voltage high-side drivers, that in turn supply drive signals to the external high-side transistors through the package terminals. External low-side transistors are driven directly by low-side drivers of the first die. If the fault protection circuit detects an excessive current, then the fault protection circuit supplies a disable signal to high-side and low-side drivers of both dice.Type: GrantFiled: November 5, 2012Date of Patent: April 7, 2015Assignee: Active-Semi, Inc.Inventors: Steven Huynh, Tsing Hsu

Publication number: 20150064817Abstract: Embodiments of the present invention provide an electrically controlled optical fuse. The optical fuse is activated electronically instead of by the light source itself. An applied voltage causes the fuse temperature to rise, which induces a transformation of a phase changing material from transparent to opaque. A gettering layer absorbs excess atoms released during the transformation.Type: ApplicationFiled: October 31, 2014Publication date: March 5, 2015Applicant: International Business Machines CorporationInventors: Kangguo Cheng, Raghavasimhan Sreenivasan
