1A8D data sheet

[KevinW]

I have a control board for a Dewalt 20 volt chain saw and I have a 1A8D ic that I believe to be a current sensor but I can't find a data sheet or any information on the exact part.
3 pins on one side and two on the other.
It may be shunted because I have solid short on the bottom two pins.

1A8D is the code marking for device INA180A2I current sense amplifier originally made by Texas instruments and more likely copied in China.

That would be the current sensing resistor. It is likely to be around 1 mOhm so it will read as a dead short unless you have a four-wire resistance meter.

Thank you.
