描述 Description

The V6300 and V6301 are CMOS devices which monitor the supply voltage of any electronic system, and generate the appropriate Reset signal. The threshold defines the minimum allowed voltage which guarantees the good functionality of the system. As long as VDD stays upside this voltage level, the output stays inactive. If VDD drops below VTH, the output gets active. When VDD rises above VTH, the output remains active for an additional 290 ms (V6301) or 50 ms (V6300). This allows the system to stabilize before getting fully active. The threshold voltage may be obtained in different versions: 2.0V, 2.4V, 2.8V, 3.5V, 4.0V, 4.5V.
