With refrigerator applications in mind, Fairchild engineers designed the FCBS0550 (500V/5A) and the FCBS0650 (500V/6A) Motion-SPM devices for less than 200W inverter motors. Each unit integrates six MOSFETs, three high-voltage ICs (HVICs) and one low-voltage IC (LVIC) into a single compact, thermally-efficient module. The junction-to-case thermal resistance for each MOSFET is a maximum of 4C/W. The built-in HVICs and LVIC offer high noise immunity and protection functions that include control circuitry, undervoltage protection and short-circuit protection through external shunt resistors (with fault signal output). The built-in HVICs simplify designs, allowing a single grounded power supply. Units are UL-certified, satisfying the basic creepage and clearance-spacing requirements for high-voltage applications. The FCBS0550 are available in a ceramic-based (44 x 26.8 mm) mini-DIP package and operate over a case temperature range of -20 to 100C.
Inforbix is leveraging its CAD and product data access technology to power up a free iPad app that lets mobile users search and access engineering data.
Unlike his friends in engineering programs, blogger Jon Titus had little need for calculus except in a few of his college physical-chemistry labs and classes.
In the wake of the Chevy Volt fire investigations, sales are down, and General Motors' (GM) CEO Dan Akerson is blaming the downturn on a spate of bad publicity.
Thanks to embedded electronics, medical devices are getting smaller and smarter than ever. Pacemakers and implantable defibrillators are now able to call physicians. MRIs, CT scanners, and ultrasound machines are gaining mobility. And the venerable Band-Aid may soon be able to detect illnesses ranging from fevers to heart arrhythmias. On February 21, join Design News senior editor Charles Murray for a wide-ranging discussion, "Embedded Angles for Medical Products," which will explore the latest developments in medical electronics. The discussion will examine advances in medical device technology and offer an inside look at the embedded electronics behind it.
