GENERAL DESCRIPTION
The ADM709 contains a power supply monitor which generates
a system reset during power-up, power-down and brownout
conditions. When V
CC
falls below the reset threshold,
RESET
goes low and holds the
μ
P in reset. On power-up the
RESET
output is held low for 140 ms after V
CC
rises above the thresh-
old. The
RESET
output remains operational with V
CC
as low
as 1 V.
Three supply-voltage threshold levels are available suitable for
+5 V, +3.3 V and for +3 V supply monitoring. The actual reset
voltage threshold is given below.
The ADM709 is available in 8-pin DIP and SOIC packages.
