Single Supply Monitors
Overview
Monitor voltage and/or current of a single power supply. 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.
