Company ams, specializing in the design of analog ICs, today announced the release of Driver LED flash for cell phones. Novelty is an important feature, which allows to obtain the maximum flash output with the battery capacity unit.
Before issuing the operating momentum to the outbreak, the driver makes short - lasting a few milliseconds - the probe pulse, during which it measures the voltage at the battery. The result of measurement is used to determine the maximum load current that can withstand without battery voltage drops below an acceptable level. This avoids a situation where because of the flash the phone reboots.The maximum current for which designed driver is 2.5 A.
According to the manufacturer, the use of AS3649 allows each situation to get maximum brightness of the flash at the same time refusing to install a bulky external power supply, such as ionistor. Designing phones simpler, because there will be no need to test the behavior of the device depending on the battery charge level and the flash (now the results of the test are stored in the phone and use it in the process).
AS3649 supplies have already begun. Price - $ 0.78 per share in the party of 1000.
