Burr-Brown Announces Industry's Only High-Side Switching Power Driver.TUCSON, Ariz.--(BUSINESS WIRE)--Nov. 13, 1998--Burr-Brown Corporation (NASDAQ NASDAQ in full National Association of Securities Dealers Automated Quotations U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on :BBRC BBRC Biochemical and Biophysical Research Communications BBRC Bellevue Breakfast Rotary Club (Washington state) BBRC Ball Brothers Research Corporation ) today announced the DRV DRV Driver DRV Drive DRV Device Driver (file name extension) DRV Democratic Republic of Vietnam DRV Darunavir (pharmaceutical drug-HIV treatment) DRV Daily Reference Value DRV Deutscher Raiffeisen Verband 102, a single integrated circuit (IC) optimized to drive electromechanical The use of electricity to run moving parts. Disk drives, printers and motors are examples. Electromechanical systems must be designed for the eventual deterioration of moving components that wear over time. The first TVs were electromechanical systems (see video/TV history). and thermal devices such as valves, solenoids, relays, heaters, and lamps used in industrial control, factory automation, and medical analysis. This device is the Company's latest addition in a new line of innovative switching power drivers. The DRV102's wide range of power driver applications include off/on control (fully open or closed), and proportional control for providing a variable opening or position to allow partial flow of fluid or gas. The DRV102 is designed to conserve power, reduce heat, and allow precise control of the power delivered at designated levels and intervals to the system. The high-side switching DRV102 provides the designer an opportunity to apply a separate unfused supply connection to each solenoid solenoid (sō`lənoid'), device made of a long wire that has been wound many times into a tightly packed coil; it has the shape of a long cylinder. in the system. The advantage is that a short on any solenoid wire will not bring down the entire system. A companion driver, the low-side switching DRV101, was introduced earlier this year and is used to conveniently accommodate system wiring where solenoids are grounded. "The DRV102 offers a complete, tested, compact solution for less than it would cost the designer to build their own," said John Brown, strategic marketing engineer at Burr-Brown. "The end goal of this growing family of switching power drivers is power conservation and the resulting increased reliability." The device features a pulse-width modulator Modulator Any device or circuit by means of which a desired signal is impressed upon a higher-frequency periodic wave known as a carrier. The process is called modulation. The modulator may vary the amplitude, frequency, or phase of the carrier. (PWM (Pulse Width Modulation) A modulation technique that generates variable-width pulses to represent the amplitude of an analog input signal. Like its fixed-width pulse density modulation (PDM) cousin, the output switching transistor is on more of the time for a ), digital input for control by microprocessor, high output drive (2.3A), wide supply range (+8V to +60V), and full protection from load faults and overheating Overheating An economy that is growing very quickly, with the risk of high inflation. . The DRV102 can be set to provide a strong initial closure, automatically switching to a "soft" hold mode for power savings and reduced heat dissipation. The device is packaged in a small 7-lead stagger-formed TO-220 and a 7-lead surface-mount DDPAK plastic power package. The DRV102 is priced at $3.60 in 1,000 piece quantities. Delivery is from stock. According to projections from Burr-Brown, the market for power driver applications will exceed $55 million in 1999.
