GENERAL DESCRIPTION
The ADM803/ADM809/ADM810 supervisory circuits monitor
the power supply voltage in microprocessor systems. They pro-
vide a reset output during power-up, power-down, and brownout
conditions. On power-up, an internal timer holds reset asserted
for 240 ms. This holds the microprocessor in a reset state until
conditions have stabilized. The RESET output remains opera-
tional with VCC as low as 1 V. The ADM803 and ADM809
provide an active low reset signal (RESET), while the ADM810
provides an active high signal (RESET) output. The ADM809
and ADM810 have push-pull outputs whereas the ADM803 has
an open-drain output, which requires an external pull-up resistor.

Figure 1. Typical Operating Circuit
Seven reset threshold voltage options are available, suitable for
monitoring a variety of supply voltages. Refer to Table I.
The reset comparator features built-in glitch immunity, making
it immune to fast transients on VCC
.
The ADM803/ADM809/ADM810 consume only 17 µA, making
it suitable for low power portable equipment. The ADM803 is
available in a 3-lead SC70; the ADM809/ADM810 is available
in 3-lead SOT-23 and SC70 packages.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although the
ADM803/ADM809/ADM810 feature proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions
are recommended to avoid performance degradation or loss of functionality.

In other microprocessor supervisory circuits, tolerances in supply
voltages lead to an overall increase in reset tolerance levels due
to the deterioration of the microprocessor reset circuit’s power
supply. The possibility of a malfunction during a power failure is
greatly reduced because the ADM803/ADM809/ADM810 series
can operate effectively even when there are large degradations
of the supply voltages. Another advantage of the ADM803/
ADM809/ADM810 series is its very accurate internal voltage
reference circuit. These benefits combine to produce an excep-
tionally reliable voltage monitor circuit.

Interfacing to Microprocessors with Multiple Interrupts
In a number of cases, it is necessary to interface many interrupts
from different devices (e.g., thermal, altitude, and velocity sensors).
The ADM803/ADM809/ADM810 can easily be integrated into
existing interrupt-handling circuits (Figure 4) or be used as a
standalone device.

INTERFACING TO OTHER DEVICES’ OUTPUT
MICROPROCESSOR
The ADM803/ADM809/ADM810 series is designed to integrate
with as many devices as possible and, therefore, has a standard
output dependent on VCC. This enables the part to be used in
both 3 V and 5 V or any nominal voltage within the minimum
and maximum specifications for VCC. Because of this design
approach, interfacing this device to other devices is simplified.

Ensuring a Valid Reset Output Down to VCC = 0 V
When VCC falls below 0.8 V, the ADM803/ADM809’s RESET
no longer sinks current. A high impedance CMOS logic input
connected to RESET may, therefore, drift to undetermined
logic levels. To eliminate this problem, a 100 kΩ resistor should
be connected from RESET to ground.
