Description
The V6330 is a CMOS device which monitors the supply voltage
of any electronic system, and generates the appropriate Reset
signal.
The gap between the two thresholds defines the
allowed voltage range. As long as V stays inside this voltage
window, the output stays inactive. If V drops below V
, or
rises above V
, the output gets active. When V enters into
the allowed range, the output remains active for an additional 50
ms (typ.). This allows the system to stabilize before getting fully
active. The lower threshold voltage may be obtained in
different versions:
2.0 V to 6 V
2.4 V to 6 V
2.8 V to 6 V
3.5 V to 6 V
4.0 V to 6 V
4.5 V to 6 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.
1)
The maximum operating temperature is confirmed by
sampling at initial device qualification.
2
Absolute Maximum Ratings
This device has built-in protection against high static voltages
or electric fields; however, anti-static precautions must 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.
