SG1543/SG2543/SG3543  
POWER SUPPLY OUTPUT SUPERVISORY CIRCUIT  
DESCRIPTION  
FEATURES  
• Over-voltage, under-voltage, and  
current sensing circuits all  
included  
• Reference voltage trimmed to 1%  
accuracy  
• SCR "Crowbar" drive of 300mA  
• Programmable time delays  
• Open-collector outputs and  
remote activation capability  
• Total standby current less than  
10mA  
This monolithic integrated circuit contains all the functions necessary to monitor and  
control the output of a sophisticated power supply system. Over-voltage (O.V.) sensing  
with provision to trigger an external SCR “crowbar” shutdown; an under-voltage (U.V.)  
circuit which can be used to monitor either the output or to sample the input line voltage;  
and a third op amp/comparator usable for current sensing (C.L.) are all included in this  
IC, together with an independent, accurate reference generator.  
Both over and under-voltage sensing circuits can be externally programmed for mini-  
mum time duration of fault before triggering. All functions contain open collector outputs  
which can be used independently or wire-ORed together; and although the SCR trigger  
is directly connected only to the over-voltage sensing circuit, it may be optionally  
activated by any of the other outputs, or from an external signal. The O.V. circuit also  
includes an optional latch and external reset capability.  
HIGH RELIABILITY FEATURES  
- SG1543  
The current sense circuit may be used with external compensation as a linear amplifier  
or as a high gain comparator. Although nominally set for zero input offset, a fixed  
threshold may be added with an external resistor. Instead of current limiting, this circuit  
may also be used as an additional voltage monitor.  
♦ Available to MIL-STD-883 and  
DESC SMD  
♦ LMI level "S" processing avail-  
able  
The reference generator circuit is internally trimmed to eliminate the need for external  
potentiometersandtheentirecircuitmaybepowereddirectlyfromeithertheoutputbeing  
monitored or from a separate bias voltage.
