LTC2914  
Quad UV/OV  
Positive/Negative  
Voltage Monitor  
FEATURES  
DESCRIPTION  
TheLTC®2914isaquadinputvoltagemonitorintendedfor  
monitoring multiple voltages in a variety of applications.  
Dual inputs for each monitored voltage allow monitoring  
four separate undervoltage (UV) conditions and four  
separateovervoltage(OV)conditions.Allmonitorssharea  
common undervoltage output and a common overvoltage  
output. The LTC2914-1 has latching capability for the  
overvoltage output. The LTC2914-2 has functionality to  
disable both the overvoltage and undervoltage outputs.
