Help ID sot23-6 chip with marking 1052U

motherboard is Nvidia Shield TV 2017

The difference with yours is in the last two digits, so you need to search for 105
Q16 - maybe transistor
Drawing a circuit through the conductors of the printed circuit board will help to understand the functional purpose.

thanks mia





where i have put 18v is from a working board. that board has the same markings 1052U.

Then for function pins layout maybe similar, but another manufacturer

Important parameters is RDS(ON), Voltage, Current.

YES! Very similar by marking code APM2605C

thanks mia for the links. i think it's the APM2605C

how would i be able to get these values from the good working board.
RDS(ON), Voltage, Current

looking at this board you can see the circled chip says M052 or M053 (image not clear)


checking Aliexpress i got APM2605C Marking:M052

If original spare parts are not available, then they are looking for replacements from other manufacturers. Datasheet parameters should be no worse.
The values of RDS (ON), Voltage, Current are indicated in the datasheet and are needed to search and select analogs from other manufacturers.
The Aliexpress photo shows a Chinese manufacturer or seller Shenzhen Rong Xinyuan Technology Co., Ltd. The marking of the transistor is different and its parameters are unknown (no datasheet). It remains to believe the seller.
I indicated earlier that the markings usually have a release date. Therefore, it is possible that m052 and m053 are the same. Maybe. Manufacturers do not agree one with the other how to components marking.

I ordered the ones from the aliexpress link.

also what do you think of this as equivalent?

DMP3050LVT

Maybe good, but with any repair, it is important not only to replace the defective part, but first of all to understand the cause of the failure and eliminate it.

update on repair.

M052 chip came and replaced, still getting hot. the i started to look under the metal shields and found 1 faulty capacitor.
replaced the capacitor and the board is working now.

so thanks mia for helping me to identify that chip marking.

behind USB ports.

my board has 4 caps


other board has 8 caps
