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 VCC
supply voltage declines below a preset threshold,
keeping reset asserted for at least 100ms after VCC
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 VCC. 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 VCC
down to +1V. These ICs provide a reset comparator
designed to ignore fast transients on VCC. 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.

Detailed Description
RESET
/RESET Output
A microprocessor’s (μP’s) reset input starts the micro-
processor in a known state. The MXD1810–MXD1813/
MXD1815–MXD1818 μP supervisory circuits assert
reset to prevent code-execution errors during power-
up, power-down, and brownout conditions (Figure 4).
Whenever VCC falls below the reset threshold, the reset
output asserts. Once VCC exceeds the reset threshold,
an internal timer keeps the reset output asserted for the
specified reset timeout period (tRP). Reset is also trig-
gered by an externally initiated rising edge on the
RESET pin (MXD1813/MXD1818), following a low signal
of 1.5μs minimum duration.
Push-Button Reset (MXD1813/MXD1818)
Many μP-based products require push-button reset
capability (Figure 5), allowing the operator, a test tech-
nician, or external logic circuitry to initiate reset. On the
MXD1813/MXD1818, a logic-low on RESET held for
greater than 1.5μs asserts a reset. RESET deasserts
following a 100ms minimum reset timeout delay
(tPBRST). A manual reset input shorter than 1.5μs may
release RESET without the 100ms minimum reset time-
out delay. To facilitate use with mechanical switches,
the MXD1813/MXD1818 contain internal debouncing
circuitry. A debounced waveform is shown in Figure 6.
Applications Information
Interfacing to μPs with Bidirectional
Reset Pins
Since the RESET output on the MXD1811/MXD1816 is
open drain, these devices interface easily with μPs that
have bidirectional reset pins, such as the Motorola
68HC11. Connecting the μP supervisor’s RESET output
directly to the microcontroller’s (μC’s) RESET pin allows
either device to assert reset (Figure 7). No external
pullup resistor is required, as it is contained within the
MXD1811/MXD1816.
Negative-Going VCC Transients
In addition to issuing a reset to the μP during power-up,
power-down, and brownout conditions, these devices
are relatively immune to short-duration, negative-going
VCC transients (glitches).

The Typical Operating Characteristics show the
Maximum Transient Duration vs. Reset Threshold
Overdrive for which reset pulses are not generated. The
graph shows the maximum pulse width that a negative-
going VCC transient may typically have without issuing a
reset signal. As the amplitude of the transient increases,
the maximum allowable pulse width decreases.
Ensuring a Valid Reset Output Down to
VCC = 0
When VCC falls below the minimum operating voltage,
push-pull structured reset sinking (or sourcing) capabil-
ities decrease dramatically. High-impedance CMOS-
logic inputs connected to the RESET/RESET pin can
drift to indeterminate voltages. This does not present a
problem in most cases, since most μPs and circuitry do
not operate at VCC below +1V. For MXD1810/
MXD1815 applications where RESET must be valid
down to VCC = 0, adding a pulldown resistor between
RESET and GND removes stray leakage currents, hold-
ing RESET low (Figure 8). The pulldown resistor value is
not critical; 100kΩis large enough not to load RESET
and small enough to pull RESET low. For MXD1812/

MXD1817 applications where RESET must be valid to
VCC = 0, a 100kΩpullup resistor between RESET and
VCC holds RESET high when VCC falls below the mini-
mum operating voltage (Figure 9).
The MXD1811/MXD1813/MXD1816/MXD1818 have
open-drain, active-low outputs with a pullup resistor
included internal to the devices. While using these
devices RESET will most likely not maintain an active
condition when the supply voltage drops below the
minimum VCC, but will drift to a nonactive level due to
the pullup resistor and the reduced sinking capability of
the open-drain output. Therefore, these devices are not
recommended for applications where the RESET pin is
required to be valid at VCC = 0.

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.
Devices are available in both leaded and lead-free packaging.
Specify lead-free by replacing “-T” with “+T” when ordering.
