Small chip burned out.

My printer had a bad connection of temp sensor and I was leaving it for a few minutes.
Then small chip near by CPU made smoke and burned out.
Maybe the connection to the sensor was short circuit.
After it was burned out, I turned the switch on.
But found there was no problem.
Even the temperature was shown at the right temperature.
So my question is
What was burned out ?
What was this chip for ?
Do somebody know the part number of this ?

looks like the VSSA fuse, which suggest a short in thermistor for bed/hotend to a heater.
think there may different sizes for different revisions of the board however
