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.
Almost every automaker has had to 'pick a side' when it comes to alternative fuel options and ways to divest from a reliance on gasoline. Fiat is looking to back compressed natural gas or liquid propane as an interim solution.
Designing and filling a new type of water bottle might take less engineering work, but the description will help kids understand how science, math, and engineering influence their lives even through things that seem mundane.
Against a backdrop of mounting product complexity and a need to keep a lid on development costs, companies are recognizing a need to make simulation a more integral part of the design process. In response, vendors in the CAD world are building out CAE functionality as part of their CAD suites while simulation vendors are building tighter integrations to leading CAD tools. Keith Meintjes, Ph.D., Practice Manager, Simulation and Analysis at CIMdata, Inc., joins Design News CAD Editor Beth Stackpole in this radio program to explore the new face of integrated CAD and CAE, how companies are benefitting from this tighter partnership between platforms, and how integrating CAE earlier in the development cycle pays off in optimized product designs.
