SGM803B/SGM809B/SGM810B
Low Power Microprocessor
Supervisory Circuit
GENERAL DESCRIPTION
FEATURES
The SGM803B, SGM809B and SGM810B are integrated
microprocessor supervisory devices which 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,
which keeps the microprocessor in the reset state until
the condition is stable.
● Superior Upgrade for MAX803/MAX809/MAX810
and ADM803/ADM809/ADM810
● High Accuracy Fixed Detection Options: 3V, 3.3V
and 5V
● Low Supply Current: 300nA (TYP)
● 150ms (MIN) Power-on Reset Pulse Width
● Reset Output Options:
Open-Drain nRESET Output (SGM803B)
Push-Pull nRESET Output (SGM809B)
Push-Pull RESET Output (SGM810B)
● Reset Valid Down to VCC = 1V
The SGM803B has an active-low open-drain nRESET
output. The SGM809B has an active-low push-pull
nRESET output and the SGM810B has an active-high
push-pull RESET output. These devices provide five
reset threshold voltage options for 3V, 3.3V and 5V
voltage monitoring.
● Fully Specified over Temperature
● VCC Transient Immunity
● -40℃ to +125℃ Operating Temperature Range
● Available in Green SOT-23-3 and SOT-23
Packages
The devices all have a low quiescent current of 300nA
(TYP). And the glitch immunity within the reset
comparator protects it from fast transients on VCC.
APPLICATIONS
The SGM803B, SGM809B and SGM810B are available
in Green SOT-23-3 and SOT-23 packages. They
operates over a junction temperature range of -40℃ to
+125℃.

ESD Susceptibility
This integrated circuit can be damaged if ESD protections are
not considered carefully. SGMICRO recommends that all
integrated circuits be handled with appropriate precautions.
Failureto observe proper handlingand installation procedures
can cause damage. ESD damage can range from subtle
performance degradation tocomplete device failure. Precision
integrated circuits may be more susceptible to damage
because even small parametric changes could cause the
device not to meet the published specifications.

Reset Timing
The reset signal is asserted low for the SGM809B and high for the SGM810B when the power supply voltage falls
below the threshold trip voltage and remains asserted for at least 150ms after the power supply voltage has risen
