V6309

The V6309 and V6319 are mi cro pro ces sor su per vi sory cir -cuits used to mon i tor the power sup plies in P and dig i tal sys tems. They pro vide ex cel lent cir cuit re li abil ity and low cost by elim i nat ing ex ter nal com ponents and ad just ments when used with 5 V pow ered or 3 V pow ered cir cuits.

These cir cuits per form a sin gle func tion: they as sert a re -set sig nal when ever the VDD sup ply volt age de clines be low a pre set thresh old, keep ing it as serted for at least 140 ms af ter VDD has risen above the re set thresh old. The only dif -fer ence be tween the two de vices is that the V6309 has an ac tive-low RESET out put (which is guar an teed to be in the cor rect state for VDD down to 1 V), while the V6319 has an ac tive-high RESET out put. The re set com parator is de -signed to ig nore fast tran sients on VDD. Re set thresh olds suit able for op er a tion with a va ri ety of sup ply volt ages areavailable.

Low sup ply cur rent makes the V6309/V6319 ideal for use in por ta ble equip ment. The V6309/V6319 come in a 3-pin SOT-23 pack age
