Need help identifying SC70 "CFT" chip on water damaged board

Hello all

My sister is a writer, and she managed to spill her hot cocoa all over her MacBook. I have cleaned and inspected the board thoroughly, and I've only found one component showing signs of damage so far.

I know its a SC70 package, its marked with "CFT", but I can't seem to track down what it is, what it does, or a replacement part. I have found similar looking components, some of which are INA213's, but I can't identify this puppy for sure.

Can someone please help me identify it?

I have attached a photo below. It's not the "actual" board but its close enough to do the trick. I have circled the damaged SMD with red at the bottom of the picture, just to the left of the fan.

*EDIT*

I just thought I would update this for future searchers looking for answers to their tricky questions.

I completed this repair after replacing the keyboard and around 15 SMD components. The computer passed it's Apple Hardware Test and ran without a hitch until we sold it in 2016. To the best of my knowledge it is still going! Have hope, ye water-damage repairers!

Jinajon, your computer is actually a MacBook Pro 13" Unibody Early 2011. The part in question is reference designator U5410, which is a TI INA213 Voltage Output, High/Low-Side Measurement, Bi-Directional Zero-Drift Series Current Shunt Monitor. You can get the datasheet from here. The part is available at places like Mouser.com as well as Digikey.com. Hope this helps, good luck.
