Overview
The SMA130
is a new compact
, triaxial acceleration
sen
sor for
non
–
safety automotive applications, packaged in a
LGA pac
k-
age. With its ultra
–
small footprint of only 2 mm x 2 mm and its
very low power consumption, it provides a cost
–
efficient one
–chip
solution especially for infotainment
systems like in
–
dash navig
a-
tion or telematic on
–
board units.
The SMA130 detects accelera
tions in three perpendicular axes
and allows tilt, motion, vibration or shock sensing regardless of
the mounting orientation of the sensor. In particular the SMA130
eliminates the need for different sensor housings for slant
–
angle
correction in in
–
dash nav
igation systems.
Product description
The SMA
130 contains a digital 1
4
–
bit triaxial acceleration
sensor
with different measurement ranges between
±
2
g and
±
16
g.
Numerous programming options, a low signal noise and a very
small footprint make the SM
A
130 a highly versatile and easily
applicable
accelerometer.
For individual adjustments to the
a
p
plication, the user can easily choose via the digital interface
between four different measurement ranges and several low
pass filtering options. In addition, a
n 8
–
bit temperature signal is
available.
An embedded self
–
test ensures signal integrity.
The sensor accepts supply voltages between 1.62 V and
3.6 V
and can be operated in a temperature
range between
–
40 °C and +85
°C.
The sensor is RoHS compliant and
qualified
according to AEC
–
Q100.
The sensor features five
power
–
safe
modes
(current consum
p-
tion between 1 μA and 66 μA)
with fast wake up times below
2
ms
. The
se user
–
programmable modes
can be used for power
–
critical applications with
low signal samp
ling
rates.
