@imicrosoldering U5860 is a TI TMP461 sensor. Here is [http://www.ti.com/lit/gpn/tmp461|the datasheet] for it. With the writing on the sensor up Pin 1 is to the top left. On your board pin 1 is the bottom left pin so the writing would face to the outside (left hand side). [image|1833996] Due to the size of the sensor,the direction of the sensor is not visible on the teardown .
