[High-tech LED News] The "BD8372HFP-M" driver IC for car LED taillights developed by the Japanese semiconductor manufacturer Rom Co., Ltd. can greatly improve the output current accuracy and increase the allowable range of LED errors, thus improving the taillight assembly process. Yield.
Rom said that the new product has been available for sampling in March 2011 at a price of 300 yen per unit, and will be put into mass production at a tentative monthly production of 50,000 units in June 2011. The pre-process plan was produced at ROHM and Optical Co., Ltd. (Okayama Prefecture), and later at ROHM Integrated Systems Co., Ltd. (Thailand).
According to reports, compared with the ordinary LED driver, the output power of the new product is 200mA, the output current is increased by about 3~5 times, and the output current precision is controlled to ±3%.
The new product adopts the source driving method, and after the driver IC board and the LED circuit board are cut to one line, the open/short detection required for the vehicle use can be easily realized. The brightness of the taillights and the brightness of the brake lights can be set independently of the independent current, which greatly facilitates the design of the vehicle taillights. The P-BUS function and the LED open/short detection protection function enrich the fail-safe function.
In addition, the development of this new product has set up a dedicated production line for the automotive market. After the automotive electrical products are greatly expanded, ROHM will further strengthen the serialization of LED driver IC products.

3500 Puffs Disposable ecig have a completely enclosed design, reducing the need for charging and replacing cartridges. The no-charge design also reduces the occurrence of faults. It is understood that with rechargeable e-cigarettes, each cartridge needs to be charged at least once and the battery efficiency is extremely low, while the design of disposable ecig can solve this problem very well.
