This device was designed to provide all the operational features of the SG1543 device 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. The voltage-sensing input comparators are identical and can be used with threshold levels from zero volts to VIN (3V). Each has approximately 25mV of hysteresis which is offset so the switching differential threshold is zero on the non-inverting input for rising levels and zero on the inverting input for falling signals. All other operating characteristics are as described in the SG1543 data sheet and application note.
