Voltage Monitor  
FEATURES  
DESCRIPTION  
TheLTC®2912voltagemonitorisdesignedtodetectpower  
supply undervoltage and overvoltage events. The VL and  
VH monitor inputs include filtering to reject brief glitches,  
thereby ensuring reliable reset operation without false or  
noisytriggering.Anadjustabletimerdefinesthedurationof

Available in 8-Lead ThinSOTTM and (3mm × 2mm)  
coupled with low supply current demand allows operation  
DFN Packages  
from higher voltages such as 12V, 24V or 48V.  
Three output configurations are available: the LTC2912-  
1 has a latch control for the OV output; the LTC2912-2  
has an OV and UV output disable feature for margining  
applications; the LTC2912-3 is identical to the LTC2912-1  
but with a noninverting, OV output.  
APPLICATIONS  
Desktop and Notebook Computers  
Network Servers  
Core, I/O Voltage Monitors
