Description
The V6300 is a CMOS device which monitors the supply voltage
of any electronic system, and generates the appropriate Reset
signal. The threshold 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 50 ms
TH
(typ.). This allows the system to stabilize before getting fully
active. The threshold voltage may be obtained in different
versions: 2.0 V, 2.4 V, 2.8 V, 3.5 V, 4.0 V, 4.5 V.

Handling Procedures
Stresses above these listed maximum ratings may cause
permanent damage to the device. Exposure beyond specified
operating conditions may affect device reliability or cause
malfunction.

The maximum operating temperature is confirmed by
sampling at initial device qualification.

Symbol Conditions This device has built-in protection against high static voltages
or electric fields; however; it is advised that normal precautions
be taken as for any other CMOS component. Unless otherwise
specified, proper operation can only occur when all terminal
voltages are kept within the supply voltage range.
