5V threshold — the rail it watches
The TPS3702CX50DDCT is a single-channel voltage detector from TI's TPS3702 family, monitoring a single supply rail with a threshold of 5V.
Temperature range and error budget
The SOT-23-6 Thin package (SOT-23-THIN) keeps the footprint small, but the thermal pad is the die-attach paddle — layout should connect it to a quiet ground plane for heat sinking, not leave it floating.
