The 600V Benchmark HEXFET® power MOSFETs have RDSon values that are 1/10 as low as industry standard types in the same package size. The devices are targeted at high-end, space constrained applications requiring high power MOSFETs, such as multi-kilowatt SMPSs in high-end computing, and telecom applications, as well as high power PFC front-ends. In these applications Benchmark reduces the number of paralleled power MOSFETs, decreases power dissipation and shrink, and eliminates heatsinking.

Improved performance and reliability are two qualities design engineers strive for, especially in the competitive, high-volume automotive industry. Low-voltage Hexfet® power MOSFETs are aimed at automotive applications including new 42V integrated starters/alternators, braking, and power steering. The company says that by using its new low-voltage planar-stripe silicon technology and "Super" series packaging, twice the silicon can be packed into the same footprint, resulting in lower R-DS(on), and a more efficient thermal path. Values of R-DS(on) range from 3 to 5 m, which, it says, are 50 to 28% lower than competing devices. As a measure of ruggedness, the Hexfet MOSFETs have avalanche energy ratings from 2,000 to 4,000 mJ, which it notes, is 4 to 7 times higher than current technology components, so designers can eliminate external passive devices to protect power MOSFETs.

The accelerator pedal sensor assembly replaces typical throttle linkages and cables by transmitting the driver's pedal inputs to the engine electrically rather than mechanically. The unit is installed in 1999 Mercedes S-class vehicles. A specially designed redundant friction cable, which produces force hysteresis, or resistance, on the bowden cable, provides a "feel" identical to a conventional pedal. If the return spring should fail, the redundant cable guarantees pedal return, although the tension is halved. The assembly also contains a redundant sensor as a backup should the primary sensor fail. The accelerator pedal module uses a Hall-effect sensor to determine the angle of the pedal. The sensor is programmable to meet specific customer requirements. Pedal functions are integrated into the sensor, including idle speed, full throttle, and kick-down pressure and switching points. The electronic signals are compatible with both analog and digital engine control units.
