Semiconductor NCV7680 consists of eight linear programmable constant current source. Using the the NCV7680 the system is designed to achieve THREE brightness levels

Semiconductor another Both devices can also be used for the above applications,LED headlamp power ballast and dual LED drive Articles NCV70521, and NCV70522 are single-chip micro-stepping motor driver with the current conversion table and SPI interface. NCV70522 also includes embedded 5 V regulator and watchdog reset function. The device can be used as a peripheral drive to accept from the microcontroller Next micro-step instructions, and motor coil current and the desired speed synchronization. The integrated SPI bus allows parameter settings and diagnostic feedback.

ON Semiconductor's NCV78663 single-chip intelligent headlamp LED driver can achieve high beam and low beam lights, daytime running lights, marker lights, the corners auxiliary lights, turn indicators and fog lamps, single-chip control . NCV78663 integrated digital dimming, SPI programmable settings and built-in diagnostics provide an integrated, energy-efficient integrated headlamp control solutions.

Semiconductor NCV7680 consists of eight linear programmable constant current source. Using the the NCV7680 the system is designed to achieve two brightness levels, brake lights, a tail lighting; optional PWM control, which is the preferred method of dimming LED. The fixed frequency PWM generator provides flicker-free lighting. Optional external ballast FET helps to achieve the requirements of the design of high-current power distribution.

    As for the the MyFord traffic system naturally fail to mention that in the high-equipped models of the 8-inch touch screen on the dashboard of two 4.2-inch LCD screen, multi-function steering wheel and central console. Everyday driving car vast majority of command operations through two sets of four arrow keys.

    With models of high LCD is not only fashionable, but also to allow motorists to hand off the wheel to complete more operations indirectly to increase traffic safety. Here let me introduce two LCD flat role.

    The speedometer left side of the LCD screen is mainly responsible for the vehicles to set up and display, the LCD screen on the right is in charge of entertainment, telephone, navigation and air conditioning functions. It is worth mentioning is that engineers will be four functions given in four colors, and beautiful at the same time increase the ease of use.

    The large space with 340W power output, SONY sound natural is good and plus 12 speaker throughout the entire vehicle for passengers to bring theater-like sound to enjoy.

    In addition, Main products: car dvd player and car dvd , are with good quality. the 2013 models Flex central touch system is also very strong, accompanied by eight inches, a central touch screen and the SYNC voice control system, the basic completion of all air conditioning and multimedia and navigation operations.

 In order to support the configuration of the LED string combination of car taillights (RCL), NCV7680 eight match output to drive the LED strings, and a resistor to set the current. The single LED string driver can ensure equal current distribution between the LED string.
