Description
The V6310 is a CMOS device which monitors the supply voltage
of any electronic system, and generates the appropriate Reset
signal. The g ap between the two thresholds defines the
allowed voltage range. As long as VDD stays inside this voltage
window, the output stays inactive. If VDD drops below VTHlow, or
rises above VTHhigh, the output gets active. When V DD 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 thresho ld 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
Applications
All microprocessor applications where an automatic restart is
required:
n Computer electronics
n White / Brown goods
n Automotive electronics
n Industrial electronics
n Telecom systems
n Hand-held systems
