Title: Tablet repair: Looking for datasheet of USB-C PD Controller EtronTech EJ898H
Post by: 0xPIT on May 11, 2020, 08:42:16 pm

Hello all,

I'm aiming to repair a tablet. Someone already used what must have been some sort of welding device at the USB-C connector.... pads are missing. Might be hard to fix.

So, I'm looking for datasheet (Pinout) of the USB-C PD Controller: EtronTech EJ898H so that I can maybe bypass and use the Tablet using an alternative power source.

tl;dr: Looking for the datasheet or pinout of EtronTech EJ898H USB-C Power Delivery controler.

Thanks!

This is great, thanks a ton!

Does not seem too trivial to bypass, though, maybe need to bodge some new USB-C connector on this one.
