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.
