Description
The V6301 is a CMOS device which monitors the supply voltage
of any electronic system, and generates the appropriate Reset
signal. The thres hold defines the minimum allowed voltage
which guarantees the good functionality of the system. As long
as V
DD
stays upside this voltage level, the output stays inactive.
If V
DD
drops below V
TH
, the output gets active. When V
DD
rises
above V
TH
, the output remains active for an additional 290 ms
(typ.). This al lows the system to stabilize before getting fully
active. The threshold v oltage may be obtained in differ ent
versions: 2.0 V, 2.4 V, 2.8 V, 3.5 V, 4.0 V, 4.5 V.
