Poly Fuse压敏电阻

Poly Fuse压敏电阻,第1张

传统的Fuse主要有三种:以大电流烧断的金属熔线(Metal Fuse)和多晶硅熔线(Poly Fuse),或是以激光烧断之金属熔线(Laser Fuse)。Fuse为电子产品中之关键性零组件,其功能为掌管备用内存(Redundancy Memory)切换,或用于射频电路(RF)中,提供可调整之电阻与电容特性(RC trimming),以及常见使用于安全码(Security Code)、电子卷标之低字码(Low Bit Count)数据储存。现有市售产品因使用激光烧断、大电流烧断等制程,往往面临不可回复性等问题,如以大电流烧断之金属熔线(Metal Fuse)或是复晶硅熔线(Poly Fuse),需以较大电流进行,将受限于烧录设备与接脚的设计,而以激光烧断之金属熔线(Laser Fuse) 仅能在芯片封装前进行,应用范围受限,且制程的良率较差。传统制程所衍生之不可回复性与不便利性俱为产业界亟欲改良之缺点,且随着半导体制程技术的进步,市场需要快速适应变化与突破限制的零组

Freescale adopts electronic control solutions purification small internal combustion engines time: 2009-12-16 08:42:33 sources: SCM and embedded systems author: freescale semiconductor company

In China, India and Brazil and other emerging markets, on a low cost two rounds and three-wheeled vehicles increasing demand. These small engine - especially vaporization two stroke design, became the mainstream of Asian small engine, but also the major sources of air pollution. A car with a two stroke engine three-wheeled taxi emissions of harmful gases, equivalent to about 50 cars modern automobile emissions caused combined.

Governments around the world are enforcing strict rules of motorcycle and outdoor equipment manufacturer required design ignited cleaner small engine. Motorcycle emerging markets are in use with Euro 3 similar emission standard. The United States environmental protection agency (EPA) enacted in small engine emission regulations strictly. According to the outdoor grid equipment industrial association, when the EPA stage 3 standard by 2015 after completely realized in the United States, is expected to 1997, compared with horizontal would come from small gasoline engine harmful emissions 95%.

Meanwhile, facing the world emission regulations and rising gasoline prices, small engine market is from mechanical carburetor system, steering more clean, efficient of electronic control and electronic fuel-injected (EFI) system. In response to a global for these ecological friendly design requirement, freescale have highly integrated simulation equipment and 16 micro controller (MCU) combined, provide economic efficient platform solutions, become small engine control ideal choice.

This platform by MCZ33812 (for control of the fuel and EFI edm and electronic fuel injection system and optimize the senior analog integrated circuit) and freescale S12 micro controller (MCU) composition. This comprehensive small engine control platform helps to reduce the harmful gases, reduce the system complexity, reduce material use and manufacturing cost, and speed up the market more quickly. Freescale small engine control target applications include for motorcycles, ZhuLiChe, scooters and three rounds of the taxi small-engine two stroke or four stroke engines. The platform is lawn mower, gardening tractor, trimming machine, milling machine, the side chain saw, focusing on snow removal machine, deciduous purging instrument, cultivating machines, generators, outside outfit motor, etc many outdoor power equipment of small engine design ideal choice.

For the more environmental clean small engine rising demand

For small engine makers, in order to satisfy the more stringent emission regulations, the forced the most practical way is using electronic ignition, electronic carburetor and ultimate EFI engine electronic control etc. Compared with the carburetor system, in small engine EFI system implementation, can reduce 65% of the most respectively of carbon dioxide, 35% of hydrocarbons and 35% of nitric oxide emissions. Meanwhile, install the EFI small engine increases horsepower and improved gasoline per unit to the number of kilometers traveled.

Widely used in small engine senior electronic control, highly integrated requirements and economic affordable components. Freescale new MCZ33812 analog integrated circuit represents the market breakthrough technology. This device combining stabilizer, injector drive and ignition pre drive, and relay and lamp drivers, the watchdog timer and reset generator etc, all of these small engine control is optimized. This excellent compositive, supported by SMARTMOS technology by freescale for engine maker reduced most 12 independent components, and for the engine manufacturers can simplify the circuit board area, while helping our clients improve their quality and reliability of products. Promote a rapid listing of reference designs

For assisting small engine market from mechanical/based on electronic control system of the carburetor steering and fuel injection, freescale provides reference to hardware/software design features of integrated system solutions, so as to speed up the development process. Freescale finished product MCZ33812 reference designs lets developers S12P micro controller based on MCZ3812 and evaluate double chip solutions, and simulation complete small engine electronic control unit (ECU). Freescale is provided for small-engine design through optimization software device drivers and engine control software. Reference design makes the test engineers and ECU hardware and software design personnel can parallel job, development process, and streamlined shorten time to market.

Powerful MCU supporting

S12 / S12X MCU series are widely used in automotive electronics market 16 architecture. MCZ33812 IC and S12P MCU for small engine control design provides ideal combination. S12P provide 16-bit MCU, while supporting the performance advantage of eight MCU entry-level pricing, low power, the electromagnetic compatibility (EMC) and code size efficiency. Extensible S12P series provides many price/performance options, and through ascension performance XGATE technology that provides access to the powerful S12XS series and S12XE device of smooth migration path. This compatibility lets the developer with flash memory and performance requirements with the increase of the ascension of their small engine Settings.
