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 stays upside this voltage level, the output stays inactive. DD If V drops below V , the output gets active. When V rises DD TH DD above V , the output remains active for an additional 290 ms TH (typ.). This al lows the system to stabilize before getting fully active.
