For mobile applications, the factory ROHM released the built-in display Pattern automatic lamp control LED driver

For mobile phones, music devices such as mobile applications, Rom of Japan (RHOM) Company issued a built-in automatic light control display LED driver Pattern driver LED, including 6 lamp BD2802GU and built-in booster circuit LED6 lamp type BD2812GU, can effectively reduce the processing burden of CPU software.

For the high demand for mobile device applications, ROHM specially developed the optimized LED6 light (using RGB LED is 2 lights) drive series BD2802GU and BD2812GU. Package for small WL-CSP (epitaxial wafer level chip size package), and the use of easy to install 0.5mm pin distance, the size of the mobile device is easy to carry. The two can be 7bit (step 128) to adjust the LED6, through the constant current DAC, low EMI, can effectively reduce the noise and flicker.

In addition, the built-in display Pattern, can automatically control the light effect, from the CPU lamp control is almost 0. Use a variety of functions to provide mobile devices with a rich expressive power of LED lights. Display Pattern can be set arbitrarily for 6 lights LED. 7bit can control the largest display 2 million 90 thousand and 7 color (R:128 * G:128 * B:128 order order order) of the color display, smoothly let LED lamp performance more abundant. At present, the drive LED6 lamp BD2802GU (2.8 x 2.8 x 1.0mm) has been shipped from the beginning of February samples, is expected to be produced in the month of July 2009, the size of the production of 1 million.
