Ecoflow Delta Max 2000 Repair - Part identification

[mslr]

Hello,
I purchased a broken Ecoflow Delta Max 2000 and I‘m on the way to repair.
Just a summary:
Got the 50Hz Overload message - This was quite simpel. There is a 12A Fuse on the inverter board which had been plown. I replaced it and the error ist gone.
Then I got a battery error - not allowing me to charge or discharge. A little bit more difficult. At the end it turned out, that the control-board (with the display) had to blown protection resistors (should be 100Ohm but was 3k). Therefore the control board could not communikate to the BMS. Changed them an I got the battery back.
Now I was able to charge by DC but not by AC.
When I plug in power to charge - the Charging power goes up to 3.800 Watt - but Battery is not charging. When I switch on the AC outlet I’m back at the overload error. AC switches off and the overload condition is restored a few seconds later.
Inverter is not affected, I could drain full power on AC with correct power on the display.
I traced the complete inverter board and it looks like that the current measurement to the Battery on the inverter board is damaged. It is a low side measurement with an Shunt of 250microOhm (4 1mOhm resistors in parallel) These shunts are connected to the inverter control board and connected to a current sensing amplifier (6-pin SMT device) with the marking 9A3LR. I checked all my sources but did not find anything with that marking - of course I could check for something that could fit but I do not want to redesign it. Checked Maxim, TI, STMicroelectronic, Microchip).
This current sensing amplifier seems to be blown. Can anybody help me identifying that part?
Thanks for the support.

Found part.
It is an TP181A3-CR compatible with INA199 or INA210. Gain is 200. Ordered replacement. Let‘s see if I can repair it.
