The lighting system on the car not only lets the driver understand the state of the car actually, having offered it in the course of safety drive even more, the condition that there must be. And new monobasic the intersection of light source and LED, for a lot of consumers is not at all non- strange, has already further expanded and applied to the car, and in the face of different demands for efficiency according to each application, choose the suitable LED products. Basically, because LED and traditional light source are except except appearance difference on, only appearing has a very great difference to output with efficiency too, so, should apply LED to the auto bulb improving, including optics design and scattered thermal design,etc., different from the design concepts of the traditional car lamps and lanterns. Car and LED succeed in carrying on integration, becomes all brand-new design concepts of car making.
The light source of the car is occupying very important positio... Read more

Ling Li belong to special company (Linear Technology Corporation) Introduce the simple and accurate low frequency clock chip LTC6991, this chip specially employs and designs regularly for the long duration. LTC6991 is the newest members of a series of TimerBloxTM general silicon timer, its integration accurate programmable Shaker and perfect circuit and logical device. An extremely wide programmable frequency domain allows the clock to the cycle operation of 9.5 hours by one 1ms. This makes LTC6991 applicable while making exposure control is counted, watchdog’s timer and periodically waking the timer up, and required assembly and work capacity are few.
LTC6991 can be set up with 1 to 3 resistors briefly, and the maximum frequency error is guaranteed less than 1.5%. LTC6991 has realized the accurate start of noiseless, first cycle (In power up Within 500 s) , and offered a kind of reset function, is used for the output pulse of cutback and exports keeping in the high...

China - -Global and leading communication, industry, medical treatment and car domain analog chip artificer and manufacturer Austrian little electronics corporation (SWX stock code: AMS) Put out multiple channel frequency shift keying of first totally Integrated 2.4 GHz (FSK) Transceiver AS3940. Through the Integrated periodic line supervisor, AS3940 can be to the Star Network (reach 8 pieces of customer end) Carry on reliable control. Low power consumption, high sensitive AS3940 message transmission rate are from 250 kbps to 2 Mbps (- 100 dBm @ 250kbps, - 92 dBm @ 2 Mbps) ,Inside has integrated the digital signal receive strength indicator (RSSI) , real time clock (RTC) And programmable clock output, Gaussian filter, phase locked loop (PLL) And loop filter.
AS3940 is 2.4 GHz transceiver of first built-in star network protocol supervisors, not merely avoid the patent fee, and more convenient use agreement pays managing to all network functions by oneself. This kind of highly ... Read more
Global power semiconductor and management scheme lead factory trader - the international rectifier company (International Rectifier, abbreviated as IR) Claimed to employ and put out firm and reliable series 600V IC to the gate drive of dymaxion car a few days ago, the application includes the piezoelectricity and the rail spray system, starter generator, electronic power steering system, fan and compressor etc. altogether.
The new series have five sections of high-speed power MOSFET and IGBT that drive IC, their source is the highest in Tap to reach 1.9A, maximum sucks electric current ability - 2.3A, has quick opening and turn-off time. Meanwhile, high electric current ability can be driven the more heavy-duty bigger switch while employing effectively by these new devices. This series of products include two semi-bridge drivers; AUIRS2184S has the fixed Dead Time of 500 ns, AUIRS21844S has 400 ns programmable Dead Time between 5 s.
