Roma Developed A Dedicated Drive For The Car Led Taillights

Semiconductor manufacturer Rohm Co., Ltd. has developed a specific driver IC "BD8372HFP-M" to expand the market for the vehicle to promote LED taillights. Development of the "BD8372HFP-M" is to ensure that the output power of 200mA, substantially more than the required 120 mA car taillights at the same time, will affect LED brightness control for the output current accuracy of ± 3%, the result is compared to the previous IC less than half, and then compared with the composition in the form of discrete components, the error is compressed in a quarter of the following, in order to achieve a substantial increase in accuracy.

Will affect LED brightness control for the output current accuracy of ± 3%, compared to the results of the IC is less than half of the past and then posed in the form of discrete components and compare, the error is compressed in a quarter of the following, in order to achieve a substantial increase in accuracy.
The new product scheduled to begin in March this year to provide samples (sample price: 300 yen / mouse), and in June 2011 the monthly production from the provisional scale of 5 million units in volume production. Pre-production base planning processes in the Roma and light Co., Ltd. (Okayama Prefecture), the latter process in the ROHM Integrated Systems (Thailand) Co., Ltd. (Thailand).

Recently, LED lights taillights modified development at an alarming rate, low power consumption, long life advantages of this background, the future will increasingly promote LED taillights of cars. In addition, LED taillights is the use of the current 10 to 20 form LED light-emitting diodes, but with the high brightness LED technology and the popularity of the penetration of cars to reduce the number of LED light-emitting diodes and other devices increase the demand for consumption. In such a market trend, even if LED driver IC, high precision, high power demand is also increasing. Therefore, the urgent need to develop high-performance LED taillights car driver.

The special LED taillights Roma developed driver IC, because to ensure that the output current of 200 mA, and the previous LED driver, the output current increases by 3 to 5 times, so that the LED's high brightness of the possible. In addition, due to the significant improvement of the output current accuracy, increases the allowable error range of LED, taillight assembly process yields a substantial improvement. Another drive by the source drive, the driver IC circuit board and LED circuit board of the tie lines, and the past of the two simultaneous drive compared to a cutting, you can easily achieve the required open-vehicle use / short circuit detection.
Again, the tail lamps and brake lights whe
n the brightness of lighting (electric current) can be freely set by the independent current settings, in large part to facilitate the design of the vehicle taillights. Function and by the P-BUS LED open / short detection protection fail-safe function can be realized and more fulfilling.
Roma thin panels used in mobile phones and other LED drivers to achieve a wide range of products of, because of their low power current, high reliability, the advantages of high accuracy, in the LED driver IC market to get customers a higher rating.

Roma with ultra-thin LED panel driver with other to achieve a wide range of products of the phone, because it low-power current, high reliability and accuracy advantages of a higher rating to get customers in the LED driver IC market. The development of new products LED driver circuit using this technology experience, and the establishment of a dedicated automotive market-oriented production lines to ensure high reliability, high quality, high reliability, the overall strength to be achieved.

 

Roma is considering seeking automotive electrical products market expected to further strengthen the series LED driver IC product markets and expanded in the future.
