PMIC: Power Management Unit - its the IC the manages the power thats comes from the power adapter in to THEA500 Mini PCB, its not a PMIC, its a dummy IC so a fake PMIC - A8038 0278100S - its probably a DC to DC convertor like on THEC64 Maxi, it probably a clone of it, the maxi does not use a PMC too, cheaper option, what's on THEC64 Maxi PCB Board - Ry1314 and it has a datasheet.. - semic-boutique.com/wp-content/uploads/2021/01/RY1314-Datasheet-V1.0.2.pdf
A8036 IC on THEA500 Mini PCB board
RY1314 IC on THEC64 Maxi PCB board
The PMC on THEA500 Mini is different to the one used in the OPI3 LTS(AXP805 PMIC) and the only part that has no details about it or datasheet so looks weird, it could give THEA500 Mini a power problem down the line, if this part blows then no power to the PCB, it looks like a cheaper Chinese part, I found it in Whatsminer(bitcoin) Boards here(never heard of them before, well not into bitcoin) - www.zeusbtc.com/ASIC-Miner-Repair/Parts-Tools-Details.asp?ID=2734
On THEC64 Mini PCB board it uses a PMIC AXP209, the proper IC(Koch Media must of changed the part because they are the company that made the hardware for RGL, look below at A20-OLINUXINO-LIME link) .
It weird is has no details because most ICs do and if they do not that means the part is not really used a lot but its probably a clone of the RY1314 IC cause it does the same thing and the IC looks like the same size but has more pins so slightly different cause of the H6, could use different DC voltage then the H3 and use 1, 2 or 3 plus pins for different volts that the H6 SoC needs so why you need a PMC.
The A8038 IC is in this box too - Eachlink H6 Mini - linux-sunxi.org/Eachlink_H6_Mini
What SUNXI says about the IC
***IMPORTANT***
Power supply recommended: 5v 3A, same as THEC64 Mini and THEC64 Maxi, all RGL Machines are all based on THEC64 Mini and thats is based on a A20-OLINUXINO-LIME(THEC64 Carousel was built on it) and they all work the same, Android kernal that boots the Buildroot OS on the NAND then it runs the carousel(Firmware) from inside its int.d folder.
Might work with a Raspberry PI PSU 5.1v 3A, but no higher, because of its PMU IC, you could overload it and blow it, this is why all RGL machines should have there own PSU, you can not treat it like its a mobile phone, it needs the right Volts and Amps to function correctly, it does not work with all phone chargers because of there voltage and amps(5v 1A) it depends on the charger and how good it is, you have to add a USB Hub to it to use a USB Keyboard with it because it only has 3 USB ports(it needed 4 USB Ports really) so 5 devices are connected(1 The USB Keyboard, 2 USB Stick, 3 THEGamepad, 4 THEMouse and 5 The USB Hub) plugged into it from powering it on so it will struggle with a 5v 1A phone changer(Samsung white or now black phone chargers are terrible with it, do not use them, no wonder they do not come with them now, Samsung phones(Galaxy) have no phone changer included now with them when you buy one of there phones), most mobile phone changers are 5v 1A because they are only used to charge a Smartphone or Tablet only, they do have fast changing mode on them but thats not use because that is 12v and has to be turn on by the phone using it, thats how it charges the phone quicker by using a higher voltage in the charger to charge the phone in 1 hour instead of 4 hours.
The Power adapter from the Amazon Fire Stick 4K works OK, I tried it on THEA500 Mini and its working OK on it so far, I thought this worked OK but no, it 5v 1A and started to have a open error:
That means its having a problem powering and opening one of the devices thats plugged into it so usually its the USB keyboard or maybe the USB Ethernet Adapter.
It does not have enough amps to open the device, this is how you know its having a problem with the power adapter powering it.
All theses RGL Minis and Full Size machines are based on Android boxes, that why when you press the power button to turn it off it goes to standby mode so waiting for you to press the remote or power button to take it out of standby, make sure it unplugged from the mains when you are not using it or add a power switch to it, it even uses a Android kernal like all the other RGL machines.

What SUNXI says about the IC
The box does not seem to come with the usual AXP 805 PMIC (typically bundled with the H6). There is an IC which looks like a PMIC, judging by the coils and the many SMD components around it. However it is much smaller than the AXP and has a rather cryptic label "A8038 8099330k". The BSP log features "probe axp is dummy" and "no pmu exist".
