LTC2930  
Configurable Six Supply  
Monitor with Adjustable  
Reset Timer, Manual Reset  
DESCRIPTION  
The LTC®2930 is a configurable supply monitor for  
systemswithuptosixsupplyvoltages. Oneof16presetor  
adjustable voltage monitor combinations can be selected  
using an external resistive divider connected to the mode  
select pin. The preset voltage thresholds are accurate  
to 1.ꢀ5 over temperature. The LTC2930 also features  
adjustable inputs with a 0.ꢀV nominal threshold.  
FEATURES  
Simultaneously Monitors Six Supplies  
16 User Selectable Combinations of  
5V, 3.3V, 3V, 2.5V, 1.8V, 1.5V and  
ꢀdꢁustable Voltage Thresholds  
Guaranteed 1.5% Threshold ꢀccuracy  
ꢀdꢁustable Reset Timeout  
Low Supply Current: 52μꢀ  
Manual Reset Pin  
The reset timeout period is adjustable using an external  
capacitor. A reset event may be generated with a manual  
reset button on the manual reset input. Tight voltage  
threshold accuracy and glitch immunity ensure reliable  
reset operation without false triggering. The RST output
