Final Electrical Specifications  
LTC1921  
Dual –48V Supply  
and Fuse Monitor  
May 2002  
U
FEATURES  
DESCRIPTIO  
The LTC®1921 monitors two independent –48V supplies,  
including their fuses, and drives up to three optoisolators  
to indicate status, in accordance with standard backplane  
specifications. Requiring only three noncritical resistors  
and optoisolators, the LTC1921 replaces multiple voltage  
comparators, a voltage reference and several precision  
resistors.  
■
Independently Monitors Two –48V Supplies for  
– Undervoltage Faults: –38.5V ±1VMAX  
– Overvoltage Faults: –70V ±1.5VMAX  
■
Accurately Detects Undervoltage Fault Recovery:  
–43V ±0.5VMAX  
■
Monitors Two External Fuses  
■
Operates from –10V to –80V  
■
Tolerates DC Faults to –100V  
The monitor features dual supply overvoltage and under-  
voltage detection circuits. The preset trip thresholds in-  
cludeovervoltage,undervoltageandundervoltagerecovery  
that are guaranteed over temperature and meet or exceed  
common backplane specifications. Additional built-in cir-  
cuitry detects the condition of supply fuses. Overvoltage  
and undervoltage detectors ignore fast supply transients,  
eliminating false detection. The LTC1921 operates from  
–10V to –80V with a typical power dissipation of less than  
10mW.  
■
Tolerates Accidental Supply Reversal to 100V  
■
Withstands Transient Voltages Up to 200V/–200V  
■
Small Footprint: 8-Lead MSOP Package  
■
Requires No Precision External Components  
■
Specified from –40°C to 85°C  
U
APPLICATIO S  
■
Telecom Backplanes or Switch Cards  
■
Networking Backplanes or Switch Cards  
■
High Voltage Fuse Monitoring  
The LTC1921 is available in an 8-pin MSOP package.
