ON Semiconductor Introduces Low Vce(sat) BJTs that Improve Power Efficiency and Lower Costs in Portable and Battery-Powered Applications.PHOENIX -- The new devices achieve equivalent Rds(on) performance compared to other discrete solutions and can reduce the cost-per-socket by as much as 10 cents A global supplier of discrete devices A discrete device (or discrete component) is an electronic component with just one circuit element, either passive (resistor, capacitor, inductor, diode) or active (transistor or vacuum tube), other than an integrated circuit. , ON Semiconductor (Nasdaq: ONNN) today introduced a new family of high performance, Vce(sat) bipolar junction transistors (BJTs) that reduce overall circuit cost while contributing to better power efficiency and longer battery life in a wide variety of portable applications -- including cell phones, PDAs, media players, notebook computers A laptop computer that weighs in a range from five to seven pounds. The term originated when laptops were routinely more than 10 pounds, and those that became lighter were placed in a special "notebook" category. In practice, notebook computer and laptop computer are synonymous. , and digital cameras. These innovative low Vce(sat) BJTs are miniature surface-mount devices featuring ultra-low saturation voltage (Vce(sat)) and high current gain capability. They are designed for use in low-voltage, high-speed switching applications where affordable yet energy-efficient control is important. Ideal applications include power management, battery charging, low drop out regulation, vibrator vibrator /vi·bra·tor/ (vi´bra-tor) an instrument for producing vibrations. vibrator an apparatus used in vibratory treatment. motors, LED backlight back·light n. A type of spotlight, used in photography, that illuminates a subject from behind. tr.v. back·light·ed or back·lit , back·light·ing, back·lights , battery management, disk drive control and camera flash. To assist portable and wireless product manufacturers -- who are under tremendous pressure to squeeze costs out of every aspect of their designs -- ON Semiconductor looked beyond analog ICs to discrete components An elementary electronic device constructed as a single unit. Before integrated circuits (chips), all transistors, resistors and diodes were discrete. They are widely used in amplifiers and other devices that use large amounts of current. for potential cost savings. By applying improved silicon technology and advanced packaging, the company developed this new series of small, cost-effective BJTs that deliver low saturation voltage performance equivalent to the Rds(on) performance of more expensive discrete solutions. "We have helped some of our customers realize a 10 cents-per-circuit cost savings by implementing the new low Vce(sat) BJTs," said Wes Reid, ON Semiconductor's product line marketing manager for the Small Signal Division. "ON Semiconductor's engineering team is also rapidly developing the next generation of low Vce(sat) BJT See bipolar. devices that will reduce equivalent Rds(on) by another 50 percent, making this cost-saving technology available to more customers and their applications." ON Semiconductor's new Vce(sat) BJTs offer high electrostatic discharge (hardware, testing) Electrostatic Discharge - (ESD) One kind of test that hardware usually has to pass to prove it is suitable for sale and use. The hardware must still work after is has been subjected to some level of electrostatic discharge. (ESD (1) (Electronic Software Distribution) Distributing new software and upgrades via the network rather than individual installations on each machine. See ESL. ) tolerance which assists in protecting sensitive components from damage. Superior electrical performance and a low temperature coefficient The temperature coefficient is the relative change of a physical property when the temperature is changed by 1 K. In the following formula, let R be the physical property to be measured, let T be the temperature of at which the property is measured. work to improve power efficiency and ultimately conserve battery power. These new transistors can further reduce the overall bill of materials The list of components that make up a system. For example, a bill of materials for a house would include the cement block, lumber, shingles, doors, windows, plumbing, electric, heating and so on. (BOM) by reducing part count in certain applications. For example, by delivering a low turn-on voltage of less than 1.0 volts (V), it may be possible to eliminate the typical charge pumps A charge pump is an electronic circuit that uses capacitors as energy storage elements to create either a higher or lower voltage power source. Charge pump circuits are capable of high efficiencies, sometimes as high as 90-95% while being electrically simple circuits. . They also enable the elimination of blocking diodes due to their bi-directional current blocking capability.
