Unknown chip controlling backlight power

Open gladshire opened this issue 1 year ago • 1 comments

I am attempting to identify the 8-pin IC that controls the latest generation Framework 13 display's backlight. The mainboard schematic here identifies it on the PCB as 'U7', with part ID 'G516A1Y51U_TSOT23-8'. On the mainboard itself, the chip has '516AF' printed on it.

I am unable to find this part or any documentation for it online. Is it misidentified in the schematic?

Thanks in advance.

It's a G516 series power switch from the brand GMT (Global Mixed-mode Technology).

However their website does not list it. http://www.gmt.com.tw/tw/product/tree.php?PL=2&SL=5&CL=10&o=0&s=0&p=1

So it's probably only sold to certain large customers in volume or something.
