Product Summary

This monolithic integrated circuit contains all the functions necessary to monitor andcontrol the output of a sophisticated power supply system. Over-voltage (O.V.) sensingwith 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 thisIC, together with an independent, accurate reference generator
