"BD8372HFP-M", a driver IC for automotive LED taillights developed by Japanese semiconductor manufacturer Romco, can significantly increase the output current accuracy, increase the allowable range of LED errors, and improve the yield of the taillight assembly process.
Rom said that the new product has begun sampling in March 2011, the price is 300 yen / only, and will be in June 2011 from the tentative monthly production of 50,000 units in volume production. The pre-process plan was produced at Rohm and Hachima Co., Ltd. (Okayama Prefecture) and later at ROHM Integrated Systems Co. , Ltd. (Thailand).
According to reports, compared with ordinary LED drivers, the new product has an output power of 200mA, and the output current is increased by about 3 to 5 times, while the output current accuracy is controlled to ±3%.
The new product adopts the source driving method. After the connection between the driver IC board and the LED circuit board is reduced to one point, the on/off detection required by the vehicle use can be easily realized. The brightness of the taillights and the brake lights can be set to independent currents, which greatly facilitates the design of the vehicle taillights. The P-BUS function and the LED open/short detection protection function further enrich the failsafe function.
In addition, the development of this new product has established a dedicated production line for the automotive market. After the substantial expansion of automotive electrical products, ROHM will further strengthen the serialization of LED driver IC products.
