CC5 (Pin 2) (LTC1326): 5V Sense Input. Used as gate  
when one or more of the supplies are below trip  
thresholds and held for 200ms after all supplies become  
valid. Also asserted after PBR is held low for more than  
2 seconds and for an additional 200ms after PBR is  
released.

the Applications Information section).  
VCC25 (Pin 2) (LTC1326-2.5): 2.5V Sense Input. Used as  
gate drive for RST output FET when the voltage on VCC3
