De scrip ion
The V6309 and V6319 are mi cro pro ces sor su per vi sory cir
cuits used to mon or the power sup plies in μP and dig al
sys ems. They pro vide ex cel ent cir cuit re i abil ty and low
cost by elim nat ng ex er nal com po nents and ad ust ments
when used with 5 V pow ered or 3 V pow ered cir cuits.
These cir cuits per orm a sin gle func ion: they as sert a re
set sig nal when ever the V
sup ply volt age de clines be ow
a pre set thresh old, keep ng it as serted for at least 140 ms
af er V
has risen above the re set thresh old. The only dif
fer ence be ween the two de vices is that the V6309 has an
ac ive-low RESET out put (which is guar an eed to be in the
cor ect state for V
down to 1 V), while the V6319 has an
ac ive-high RESET out put. The re set com para or is de
signed to ig nore fast tran sients on V
. Re set thresh olds
suit able for op er a ion with a va i ety of sup ply volt ages are
avail able.
Low sup ply cur ent makes the V6309/V6319 ideal for use
