Circuit operation: This is the source circuit “classic” that we will meet all Hoai mAh power source in the laptop as RAM, CPU Vcore Power, power chipset, VGA chip source … As with branch branch quite like 3v3 5v so I just draw a branch lqv77 which stands for the second 5v 3v3 and 5v source. Should View: click the source circuit and all circuits on the power source Charge ABAT and before reading this article. As presented in ” source circuit size , “IC 5v 3v3 will take on the power source circuit ADBAT ADBAT from tier to then create a source of 5V AL 3v3 circuit low voltage to the pin into the source of the SIO chip. SIO chip will EN3 and EN5 ordered to active IC 5v 3v3 gives 2 3v3 and 5v source. This pattern is commonly found in laptops today. Another form, power supply 5v straight AL create EN3 and EN5 for the second leg to free open source and free to run this IC 5v 3v3, 3v3 then retrieve the source for SIO (As used Max8724 DV6000 user). Often the two sources will have before, but some high-end line, even two sources only after I click the power button. But mostly, it is still the “first level”. When 3v3 and 5v power generated, the signal was OK PWRGD will be reported back to the SIO chip or chip Nam. component parts of the circuit: is written …
