March 4, 2013 -Austrian Microelectronics (SIX stock code: AMS), a global leader in the design and manufacture of high-performance analog ICs for the consumer and communications, industrial and medical, and automotive applications industries, today announced the launch of a The new intelligent LED driver maximizes the brightness of the flash of the mobile phone camera, and at the same time ensures that the battery voltage of the mobile phone will not fall below the minimum operating voltage. The AS3649 LED driver has an innovative "diagnostic pulse" function-before the flash is activated, an instantaneous large current pulse lasting several milliseconds is issued. Through these current pulses, the driver will measure the instantaneous voltage of the mobile phone battery to learn the maximum driving current the battery can support, up to 2.5A, to ensure that the flashlight does not cause the mobile phone to restart due to too low voltage. Based on the advanced analog sensing technology of Austrian Microelectronics, AS3649 can accurately measure the voltage and current of the battery, so that it can achieve accurate measurement under any specific conditions to obtain the best LED drive current. AS3649 can maximize the brightness of the mobile phone flash without the need for bulky auxiliary power sources such as super capacitors. Users can obtain higher image quality and higher resolution. When shooting fast-moving objects, the shutter speed can be increased to obtain sharper and clearer images. The newly launched AS3649 LED driver can also significantly reduce the engineering investment and software development investment of mobile phone manufacturers in LED flash. Today, mobile phone manufacturers need to fully test each model of LED flash system under different conditions of use and different operating voltages. Then the test results are encoded and stored in the mobile phone software in a form of look-up table. Whenever the flash is required, the mobile phone processor must first read and evaluate the safe drive current value from the pre-stored data. The AS3649 with the introduction of "diagnostic pulse" technology can save all these engineering investments, because it can measure the actual behavior of the battery when it is in use, without the need to sample and evaluate these in advance. AS3649 is specially developed for next-generation mobile phone cameras using higher brightness LEDs. It can supply up to 2.5A for a single LED or up to 1.25A for two LEDs respectively. AS3649 provides effective thermal management through a current source and an on-board NTC (temperature sensor). If it detects that the temperature exceeds the preset value, it will automatically reduce the LED drive current. Ronald TIngl, Senior Marketing Manager of Austrian Microelectronics, said: "Consumers are very concerned about camera performance when choosing a mobile phone. This is a key element. AS3649 allows mobile phones to take photos taken in a dark environment to achieve the best brightness, while also It will help mobile phone manufacturers avoid the huge investment in testing all components under high driving current. " Supply The AS3649 smart LED flash driver is now in mass production. Technical Support The demo board for AS3649 is now available.
