Download English PDF Datasheet for ANA618 Solar Lawn Light/LED Controller

Looking for an English version PDF of the datasheet for ANA618? Search no further, here it is! 🙂

Recently, I picked up a few solar-powered lawn lights from a budget shop, to test if they were any good and what’s in it. Being a curious hobbyist and an electronics enthusiast, I opened up one of the lamps to take a look inside. Well, I found that it uses a chip ANA618. So, as usual, I was curious what were the functionality of the ANA618. I searched high and low for its document, but was unable to find an English version that provided more information about this illusive little chip.

What I did find, was the Chinese version of the datasheet after a long search, and since I could read Chinese pretty okay, and I know many of you out there had the same questions about what on earth does this chip do? What is the pin out like? Is it that colored resistor/inductor thingy really an inductor or a resistor?  I have decided to translate it, for your convenience. I have tried to translate to the best of my understanding, so if there were errors in the datasheet, the same error will also be translated. :P. Okay, with that, let’s start!

Here’s my solar lamp’s components and values that I found after tearing it apart:

– ANA618 chip (44049)
– 1.2V, 80mAH Ni-MH cell
– 260uH inductor (colored), 10% tolerance
– Orange LED x 1

Oh, by the way, I also read somewhere (additional info) that the ANA618 can drive between 1 to 3 LEDs, and output voltage is between 0.85 and 1.5V.

For the more “official” specifications of the enigmatic ANA618 chip:
