SS8037/8(G)
Microprocessor Reset IC
FEATURES
Precision monitoring of +3V, +3.3V, and +5V
power-supply voltages
DESCRIPTION
The SS8037/8 are microprocessor (µP) supervisory
circuits used to monitor the power supplies in µP and
digital systems. They provide excellent circuit reliability
and low cost by eliminating external components and
adjustments when used with +5V, +3.3V, +3.0V- pow-
ered circuits.
These circuits perform a single function: they assert a
reset signal whenever the V
CC
supply voltage declines
below a preset threshold, keeping it asserted for at least
140ms after V
CC
has risen above the reset threshold.
Reset thresholds suitable for operation with a variety of
supply voltages are available.
The SS8038L has an open-drain output stage, while the
SS8037H/L have push-pull outputs. The SS8038L’s
open-drain
RESET
output requires a pull-up resistor
that can be connected to a voltage higher than V
CC
. The
SS8037L has an active-low
RESET
output, while the
SS8037H has an active-high RESET output. The reset
comparator is designed to ignore fast transients on V
CC
,
and the outputs are guaranteed to be in the correct logic
state for V
CC
down to 1V.
Low supply current makes the SS8037/8 ideal for use
in portable equipment. They are available in a 3-pin
SOT23-3 package.
