LOW-VOLTAGE SUPERVISORY CIRCUIT

This device SG1544 SG2544/SG3544 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 monitor either the output or sample the input line voltage; and a third op amp Comparator usable for current sensing are all included in this IC, together with an independent, accurate reference generator.
