SGM803/SGM809/SGM810
Microprocessor Supervisory Circuit
GENERAL DESCRIPTION
FEATURES
The SGM803, SGM809 and SGM810 are integrated
● Superior Upgrade for MAX803/MAX809/MAX810
microprocessor supervisory devices. Compared with
the design using a single IC or discrete components,
this integration design has the advantage of improving
and ADM803/ADM809/ADM810
● High Accuracy Fixed Detection Options: 1.8V,
2.5V, 3V, 3.3V and 5V
● Low Current Consumption: 13μA (TYP)
system stability and accuracy.
The devices can be reset under power-up, power-down
or even voltage reduction brownout conditions. When
VCC is as low as 1V, the reset output can still operate.
On the power-on state, the internal timer maintains a
240ms reset assertion that keeps the microprocessor in
the reset state until the condition is stable.
● 150ms (MIN) Power-On Reset
● Reset Output Options:
Open-Drain RESET Output: SGM803
Push-Pull RESET Output: SGM809
Push-Pull RESET Output: SGM810
● Reset Assertion Down to 1V VCC
● -40℃ to +125℃ Operating Temperature Range
The SGM803 has an open-drain ����������
RESET output that
● Available in Green SOT-23-3 and SOT-23
push-pull RESET output. All devices provide eight reset
APPLICATIONS
needs a resistor pulled up to VCC. The SGM809 has a
���������� output. And the SGM810 has a
push-pull RESET
threshold voltage options for 1.8V, 2.5V, 3V, 3.3V and
5V voltage monitoring.
The devices also feature excellent transient immunity to
ignore fast VCC transients. Low quiescent current
makes the SGM803, SGM809 and SGM810 very
suitable for battery-powered applications.
The SGM803, SGM809 and SGM810 are available in
Green
SOT-23-3
and
SOT-23
packages.

OVERSTRESS CAUTION
Stresses beyond those listed in Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to
absolute maximum rating conditions for extended periods
may affect reliability. Functional operation of the device at any
conditions beyond those indicated in the Recommended
Operating Conditions section is not implied.
ESD SENSITIVITY CAUTION
This integrated circuit can be damaged by ESD if you don’t
pay attention to ESD protection. SGMICRO recommends that
all integrated circuits be handled with appropriate precautions.
Failure to observe proper handling and installation procedures
can cause damage. ESD damage can range from subtle
performance degradation to complete device failure. Precision
integrated circuits may be more susceptible to damage
because very small parametric changes could cause the
device not to meet its published specifications.
DISCLAIMER
SG Micro Corp reserves the right to make any change in
circuit design, or specifications without prior notice.
