Andigilog(R) Announces ThermalEdge(TM) Technology; Builds on Intelligent Thermal Management Solutions for More Reliable, Cooler and Quieter PCs.SAN FRANCISCO San Francisco (săn frănsĭs`kō), city (1990 pop. 723,959), coextensive with San Francisco co., W Calif., on the tip of a peninsula between the Pacific Ocean and San Francisco Bay, which are connected by the strait known as the Golden -- New Digital Temperature Sensors with Integrated Fan Control and Motor Controller Designed to Meet New Requirements for Controlling Heat Andigilog(R), the fabless semiconductor company A fabless semiconductor company specializes in the design and sale of hardware devices implemented on semiconductor chips. It achieves an advantage by outsourcing the fabrication of the devices to a specialized semiconductor manufacturer called a semiconductor foundry or "fab. providing intelligent thermal management solutions, today announced Andigilog ThermalEdge(TM) technology to enable accurate temperature sensing, precision system control and acoustic and cooling management for computer subsystems. Two new integrated circuits, based on ThermalEdge technology, will begin sampling this month for desktop and notebook PCs and other computing systems. "Industry trends such as smaller system size, faster processors and quieter PC initiatives make monitoring and controlling heat one of the designer's biggest challenges," noted Bill Sheppard, president and chief executive officer of Andigilog. "Integrated approaches such as Andigilog ThermalEdge technology offer new ways to help solve these problems in an efficient and cost-effective way by incorporating thermal management intelligence throughout the system." Andigilog aSC7512 Features The Andigilog aSC7512 system controller integrates remote temperature sensing with automatic fan speed control on-chip to maintain and optimally manage CPU CPU in full central processing unit Principal component of a digital computer, composed of a control unit, an instruction-decoding unit, and an arithmetic-logic unit. temperature. It can be easily designed into today's motherboards. The aSC7512 controller's highly accurate sensing of +/- one degree Celsius allows for more accurate monitoring so the fan is used more efficiently, conserving power and reducing operating noise. The chip supports three- and four-wire fans and includes a digital filter to smooth temperature readings for more efficient fan operation. The sensor also can notify the system of readings outside of programmed limits. Other features include multiple system alerts and a fan tachometer tachometer (tăkŏm`ətər), instrument that indicates the speed, usually in revolutions per minute, at which an engine shaft is rotating. input to measure fan speed. Andigilog aMC8500 Features The new Andigilog aMC8500 controller provides highly integrated motor control for brushless DC fan applications, such as the newest PCs based on the BTX (Balanced Technology EXtended) A motherboard design from Intel introduced in 2004 that supersedes the ATX. Unlike the ATX, the placement of all chip sockets in the BTX is defined in order to provide sufficient air flow over the processor and display adapter. small form factor. The aMC8500 provides all functions to drive a one-amp brushless DC fan. Integrated on-chip are dual 0.5 ohm ohm (ōm) [for G. S. Ohm], unit of electrical resistance, defined as the resistance in a circuit in which a potential difference of one volt creates a current of one ampere; hence, 1 ohm equals 1 volt/ampere. MOSFET (Metal Oxide Semiconductor Field Effect Transistor) The most popular and widely used type of field effect transistor (see FET). MOSFETs are either NMOS (n-channel) or PMOS (p-channel) transistors, which are fabricated as individually packaged motor drives, selectable slope for efficient speed control capable of accepting both digital and analog 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 signals, programmable minimum speed setting, Hall amplifier with proprietary noise immunity circuitry and selectable automatic low-current power-down mode for mobile applications.
