Microprocessor Supervisory
Circuit in 3-Pin SOT23
GENERAL DESCRIPTION
FEATURES
− Precision Voltage Monitor: 2.5V,3 V, 3.3 V, 5 V
Options
− Superior Upgrade for MAX803/MAX809/MAX810
and SGM803/SGM809/SGM810
− Fully Specified over Temperature
− Low Power Consumption (17μA Typ)
− Reset Assertion Down to 1 V VCC
− 160 ms Min Power-On Reset
The SGM803/SGM809/SGM810 supervisory circuits
monitor the power supply voltage in microprocessor and
digital systems. They provide 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
output remains
RESET
operational with VCC as low as 1 V. The SGM803/SGM809
provides an active low reset signal ( ) while the

Output (SGM809)
SGM810 provides an active high signal (RESET) output.
The SGM809/SGM810 have push-pull outputs, whereas the
SGM803 has an open-drain output, which requires an
external pull-up resistor.
RESET
− Compact 3-Pin SOT23 Package
Seven reset threshold voltage options are available suitable
for monitoring 2.5V, 3V, 3.3V, and 5V supply voltages.
The reset comparator features built-in glitch immunity,
making it immune to fast transients on VCC
.
The low supply current of typically 17µA makes the
SGM803/SGM809/SGM810 ideal for use in portable, battery
operated equipment. They are available in the 3-pin SOT23
package.

APPLICATION NOTES
INTERFACING TO OTHER DEVICES’ OUTPUT
The SGM803/SGM809/SGM810 series is designed to integrate
with as many devices as possible and, therefore, has a
standard output dependent on VCC. This enables the parts to
be used in both 3 V and 5 V, or any nominal voltage within the
minimum and maximum specifications for VCC. This design
simplifies interfacing this device to other devices.
BENEFITS OF AN ACCURATE RESET
THRESHOLD
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 SGM803/
SGM809/SGM810 series can operate effectively even when
there are large degradations of the supply voltages. Another
advantage of the SGM803/ SGM809/SGM810 series is its very
accurate internal voltage reference circuit. These benefits
combine to produce an exceptionally reliable voltage monitor
circuit.
ENSURING A VALID RESET OUTPUT DOWN TO
VCC = 0 V
When VCC falls below 1.0 V, the SGM803/SGM809
no
RESET
longer sinks current. A high impedance CMOS logic input
connected to may, therefore, drift to undetermined logic
RESET
levels. To eliminate this problem, a 100kΩ resistor should be
connected from
to ground.
RESET
INTERFACING TO MICROPROCESSORS WITH
MULTIPLE INTERRUPTS
VCC
In a number of cases, it is necessary to interface many
interrupts from different devices (for example, thermal, altitude,
and velocity sensors). The SGM803/SGM809/SGM810 can
easily be integrated into existing interrupt-handling circuits, as
shown in Figure 1, or can be used as a standalone device.
