General Description
The MXD1810–MXD1813/MXD1815–MXD1818 family of
microprocessor (μP) reset circuits monitor power sup-
plies in μP and digital systems. These devices provide
excellent circuit reliability and low cost by eliminating
external components and adjustments when used with
+2.5V/+3.0V/+3.3V (MXD1815–MXD1818), and +5V
(MXD1810–MXD1813) systems.
These circuits assert a reset signal whenever the V
CC
supply voltage declines below a preset threshold,
keeping reset asserted for at least 100ms after V
CC
rises above the reset threshold. The MXD1813/
MXD1818 also keep reset asserted for at least 100ms
after the output is momentarily pulled to GND by an
external push-button switch.
The MXD1812/MXD1817 have an active-high push-pull
RESET output. The MXD1810/MXD1815 (push-pull) and
MXD1811/MXD1813/MXD1816/MD1818 (open-drain)
have an active-low
RESET
output. The open-drain
devices (MXD1811/MXD1813/MXD1816/MXD1818)
have an internal pullup resistor to V
CC
. The
MXD1813/MXD1818 feature a debounced manual reset
feature that asserts a reset if the
RESET
pin is pulled
low for more than 1.5μs. When used to initiate manual
reset,
RESET
debounces signals from devices such as
mechanical switches. For devices with this feature, the
release of the external switch triggers the reset period.
The MXD1810–MXD1813/MXD1815–MXD1818 are
guaranteed to output the correct logic state for V
CC
down to +1V. These ICs provide a reset comparator
designed to ignore fast transients on V
CC
. Reset
thresholds are available between +2.18V and +4.62V.
These small, low-power (4μA) devices are ideal for use
in portable equipment. All are available in space-saving
3-pin SC70 and SOT23 packages, and are specified
from -40°C to +105°C.

The MXD1810–MXD1813/MXD1815–MXD1818 are available
with factory-set V
CC
reset thresholds from +2.18V to +3.06V
(MXD1815–MXD1818) and +4.12V to +4.62V (MXD1810–
MXD1813). Choose the desired reset-threshold suffix from the
Reset Threshold Table and insert it in place of the “_ _” follow-
ing “R” in the part number. All devices are available in tape-
and-reel only in 2500 unit increments. Other threshold voltages
may be available. Contact factory for availability.
