illuminating interruption
Examining the temperature function can avoid illuminating interruption
Lead a temperature protection of lead temperature expiration the mode come from two greatest parts around, opposite the heat of its creation while firstly being to use Gao Liang Du LED to do light source is also higher.When this kind of LED at applied,LED and OLED although the usage number that can send out enough light and effectively reduce LED, another side effect produced by it is hot.Under the normal usage condition, how much LED the electric currents will produce many high temperatures to LED are predictable.But while breaking down occurrence, leading the high temperature will make LED bright degree creation Shuai’s reducing even will damage LED, the IC beard contains the function to detect temperature at this time, be detect excrescent heat, can lower LED electric current but lower a bright degree and make its temperature lowered, when needing temperature and continuously being as low as can accept value again raise a LED bright degree, this protection function can avoid cause because of the excrescent temperature of illuminate break off;Opposite of may also stop LED output the supply of electric current to make illuminate to break off.Secondly, it is short-circuit or other to make the IC taken place to be LED abnormality of heat,finance mangaing trouble at this time beard from IC it detects action over the temperature protection to protect abnormality action of keep on occurrence to avoid a related safety problem occurrence.
Give attention to both high LED to drive electric current|electric current equilibrium high integration degree the solution big exhibition artistic skill
LED replaces a cold cathode light, tube’s(CCFL) being used as to carry on the back a light source application is more than 10 inches of big size front-panels at the notebook, desktop display, and television…etc., its LED carry light source module on its LED’s back of carry on the back light drive an IC protection function the integration seem to be particularly important more and take a comprehensive view of the preceding context description, the LD7889 can aim at the Tuo rushes toward of the importation and exportation and LED carry on the back only provide one complete and overall protection,investment and financeand it for a will rise to press to configuring and electric current the equilibrium height integrates of LED solution, can aim at each the LED electric current provides high accuracy of electric current balance degree(<2%), high LED electric current it drive ability, like each LED string=240 milli- ampere(mA), can also provide for 3D(3 Ds) application like 2, 400 milli- ampere|each one LED of the in a twinkling high electric current drive ability.It overall of expired protection function and give attention to both high LED to drive the high accuracy of electric current ability and electric current balance consideration under,Quiet quiet like you the LD7889 really carries on the back for an excellent LED only drive a solution.
