——— MC3424, —-.C - -. MC3424A MC3524, MC3524A MC3324, MC3324A I ~ ; POWER SUPPLY suPgRvlsoRY c! RcuiT/ DUAL-VOLTAGE CON! PARATQR The MC3424 seriesisa dual-channel super~isory circuit, consisting of two uncommitted input comparators, a reference, otdtput comparators, with high current Drive ar)d !r}dicator outputs for eac!~ channel. The input comparators feature programmable k)ys~eresis, high common-mode rejection, and wide commoYI-rnode range, capable of comparing at ground potentia! with single-supply operation. Separate De/ay pins are provided tO increase noise immunity by de[aying atiivation of the outputs. A2.5 V bandgap vo!tage reference or other exteris pinned-out for referertci!~g the input comparators, nal functions. Independent high current Drive and Indicator ~utputs for each channel can source and sink up to 300 mA and 30 mA respectively, Cfd OS/TTL compatible digital inputs provide Reii;ote .,~,:*~ + ~~,+, Activation of each chann~l’s outputs.
