SG1548/SG2548/SG3548  
QUAD POWER FAULT MONITOR  
DESCRIPTION  
FEATURES  
Monitors four DC voltages and the AC line  
Precision 2.5V ±1% low-drift reference  
Fault tolerance adjustable from ±5% to ±40%  
±3% trip threshold tolerance over temperature  
Separate 10mA, 40V overvoltage, undervoltage  
and AC line fault outputs  
Fault delay programmable with a single capacitor  
30mV comparator hysteresis to prevent oscilla-  
tions  
The SG1548 is an integrated circuit capable of monitoring up to four  
positive DC supply voltages simultaneously for overvoltage and  
undervoltage fault conditions. An on-chip inverting op amp also  
allows monitoring one negative DC voltage. The fault tolerance  
window is accurately programmable from ±5% to ±40% using a simple  
dividernetworkonthe2.5Vreference. Asingleexternalcapacitorsets  
the fault indication delay, eliminating false outputs due to switching  
noise, logic transition current spikes, and short-term AC line interrup-  
tions. An additional comparator referenced to 2.5V allows the AC line  
to be monitored for undervoltage conditions or for generation of a line  
clock. The comparator can also be used for programmable  
undervoltage lockout in a switching power supply. Uncommitted  
collector and emitter outputs permit both inverting and non-inverting  
operation. External availability of the precision 2.5V reference and  
open-collector logic outputs permit expansion to monitor additional  
voltage using available open-collector quad comparators.  
On-chip inverting op amp for negative voltage  
Open-collector output logic or expandability  
Operation from 4.5V to 40V supply  
HIGH RELIABILITY FEATURES - SG1548  
Available to MIL-STD-883  
Radiation data available  
LMI level "S" processing available
