9.3.3 Internal Junction Temperature Sense (TJ_SENSE) Pin

The RGT package includes an internal, junction-temperature sense pin (TJ_SENSE). This pin is a temperature-dependent current source from the positive supply into one side of the internal resistor, where the other side of the internal resistor is connected to pin 5 (GND), the PD logic reference pin on the die. For simplicity, and to keep the TJ_SENSE output ground referenced, tie pin 5 to ground (internally, the PD logic reference pin). If pin 5 is tied to a voltage in the same range as the REF pin voltage for the DDA package, the output of the TJ_SENSE voltage and input threshold voltages of the PD pin are level shifted.
