Overview

SG1544/SG2544/SG3544 LOW-VOLTAGE SUPERVISORY CIRCUIT DESCRIPTION This device was designed to provide all the operational features of the SG1543/ 2543/3543 devices but with the added advantage of uncommitted inputs to the voltage sensing comparators.
This allows monitoring of voltage levels less than 2.
5 volts by dividing down the internal reference supply.
In all other respects, the SG1544 series is identical to the SG1543 series.
These monolithic devices contain all the functions necessary to monitor and control the output of a sophisticated power supply system.
Over-voltage sensing with provision to trigger an external SCR “crowbar” shutdown; an under-voltage circuit which can be used to...
