to base of Q108 Transistor and base of Q114 Transistor. The collector voltage becomes 1v8.
When the +3V3_stb voltage decreases below the 2V6 Q110 Transistor goes OFF condition so FETs
become ON. Q107 FET shorts 1V8 digital to ground and system is reset condition.
Another reset condition becomes when the S_Reset port is active. While S_Reset port is active, FETs
become ON. 1V8 digital is shorted to ground.
All the supply architecture of the UOC3 is as follows;
