ROHM released the built-in graphics data display LED driver BD2802GU/12GU

ROHM Corporation (headquartered in Kyoto) recently, for all mobile phone devices, car audio equipment as the representative, developed by the installation of automatic lights control function (built-in graphics data), CPU software can not assume load control lights LED driver IC series. The development of the product line has LED6 lights BD2802GU (2.8 x 2.8 x 1.0mm) and LED6 lights built-in boost circuit BD2812GU (3.1 * 3.1 * 1.0mm). BD2802GU this new product has begun to supply samples (sample price: 150 yen /), starting in January this year, the monthly production of 500 thousand large-scale production. At the same time, BD2812GU from February 2009 began to supply samples (sample price: 250 yen /), will begin in July 2009 to produce the size of the month of mass production in 1 million. The production process in the process of ROHM Corporation (Hamamatsu Shizuoka), the latter process in Fukuoka ROHM Corporation (Fukuoka county) completed.

Now LED lights, all electronic products demand greatly outstanding performance dint but, because the traditional LED driver IC no lights control function, it is difficult to control the change of current small, reduced LED lights control freedom, make eyes will be uncomfortable feeling and other issues. In this case, although the LED driver IC has been installed to increase the lantern function, but the product line is still insufficient, limiting the user's freedom of application. At the same time, it is necessary to face the need for complex LED lantern noise generated by the measures, or in the process of color control when the load increased by CPU.

ROHM in order to meet these requirements, in view of the large demand mobility machine, the development of LED6 lights (RGB LED2 lights) drive IC series BD2802GU and BD2812GU. Due to the use of 0.5mm pin spacing type small package size WL-CSP (wafer level specification size patch package), easy to load in mobile devices. Moreover, the two series of LED6 lights have a 7bit gradient (level 128), according to the DAC constant current to achieve a low EMI clutter, reducing noise and visual discomfort. At the same time, according to the built-in graphics data display, can automatically control the lantern, so that the control of CPU lights is almost zero, so that the application of multi-functional electronic products enrich the performance of the LED lantern. Because the display graphics can be individually set to 6 LED lights and 7bit (level 128) resolution, can control the most about 2 million 90 thousand and 7 color (R:128step * G:128step * B:128step) the picture, can display smooth and rich LED lighting effect. In addition, the BD2802GU and BD2812GU components to control the location of the change, can correspond to more than the expansion of the lights and more large-scale decorative lights.
