Overview

SG1543/SG2543/SG3543 Power Supply Output Supervisory Circuit Description 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 minimum time duration of fault before trig...
