half-bridge solution - the Ultra FRFET family- optimizes designs by providing
best-in-class reverse recovery time (trr) of 35ns - 65ns and the industry's
smallest reverse recovery current (1.8 - 3.1A). These devices are part of a
comprehensive portfolio of MOSFETs that offer designers a wide range of
breakdown voltages (-500V to 1000V), state-of-the-art packaging and
industry-leading FOM to deliver efficient power management anywhere electronic
power conversion is needed. Fairchild's Ultra FRFET (Ultra Fast recovery
MOSFET) is an industry first. Ultra FRFET works well with less than four diodes
in high voltage backlight inverter and reduces costs in high voltage backlight
inverters by approximately $0.20. Potential savings are expected to be over
$26M in 2010 because the production of CCFL backlit LCD TV is 130M sets. The
combination technology of lifetime control process and UniFETTM mosfets achieves
soft reverse recovery characteristics and big diode dv/dt immunity guaranteeing
20V/ns compared with 4.5V/ns of normal MOSFET. The soft reverse recovery characteristics
improved EMI characteristics in LCD TV sets and big diode dv/dt immunity
improved system reliability during high frequency operation at high
temperatures. When compared to alternate solutions offering a typical gate
charge of only 16nC, the Ultra FRFET products are instrumental in reducing the
turn-on and turn-off losses of the MOSFET through its significantly lower gate
charge (Qg(typ) = 11nC). These products also feature a robust dv/dt immunity of
20V/ns, ensuring reliability and strong EMI performance to protect the LCD TVs
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
