SGM8139
Low Power, Low Voltage
PIR and Vibration Sensor AFE
GENERAL DESCRIPTION
The SGM8139 is a low voltage low power analog front
end designed for PIR and vibration sensors. This part
integrates two high input impedance operational
amplifiers, window comparator, state control logic, a
delay timer, a latch timer, a voltage reference and high
current output stages. It can be used in various sensors,
delay controllers as well as wake-up circuit in low
power consumption systems.
Many industrial and building automation systems use
motion detectors to control different functions based on
human presence. Using SGM8139 with proper PIR
sensor, it is easy to build a compact passive infrared
detection system. The output stage of SGM8139 can
easily drive different types of lights, buzzers, automatic
doors, fans and white goods with programmable timers.
It is especially suitable for office buildings, hotels,
shopping malls or automatic lighting and alarm systems,
as well as intrusion detection. SGM8139 can be used
for motion detection and room monitors in a smart
home system as an ultra-low power wake-up block.
SGM8139 can be used to condition the vibration sensor,
providing a trigger signal to system.
SGM8139 is specifically designed to operate over a
wide range of supply voltage from 1.4V to 5.5V.
SGM8139 draws only 6μA supply current. It is ideal for
applications powered by single cell or dual cell alkaline
battery.
With two operational amplifiers, window comparators,
and delay/lockout timers adjustable through external
RCs, SGM8139 can both process the PIR output signal
effectively and provide good anti-interference performance.
The SGM8139 is specified for the -40to +85
industrial temperature range. The SGM8139 is
available in Green SOIC-16 and TQFN-2.5×2.5-16L
packages. The TQFN package makes it ideal for
portable electronic products with area constrained PC
boards.

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 if ESD protections are
not considered carefully. 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 even small parametric changes could cause the
device not to meet the published specifications.
