V6300
V6301
Ultra Low Power 3-Pin Power-On Reset IC
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 V
DD
stays upside this
voltage level, the output stays inactive. If V
DD
drops below
V
TH
, the output gets active. When V
DD
rises above V
TH
, 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.
