ESCRIPTION
The SMB365 is a triaxial low-g acceleration sensor for consumer market applications. It allows
measurements of static as well as dynamic accelerations. Due to its three perpendicular axes it
gives the absolute orientation in a gravity field. As all other Bosch inertial sensors, it is a two-
chip arrangement. An application-specific IC evaluates the output of a three-channel microme-
chanical acceleration-sensing element that works according to the differential capacitance prin-
ciple. The underlying micromachining process has proven its capability in more than 100 million
Bosch accelerometers and gyroscopes so far.
The SMB365 provides a digital 10bit output signal via an SPI interface. With an appropriate SPI
command the full measurement range can be chosen to 2g or 10g. A first-order filter with a
pole-frequency of 50Hz is included to provide preconditioning of the measured acceleration
signal. Typical noise level and quantization lead to a sensitivity resolution of 4mg or an accuracy
of 0.3° in an inclination sensing application, respectively. The current consumption is typically
600
μ
A at a supply voltage of 2.5V. Furthermore, the sensor can be switched into a low-power
mode where it informs the host system about an acceleration change via an interrupt pin. This
feature can be used to wake-up the host system from a sleep mode.
The sensor also features full self-test capability. It is activated via SPI command which results in
a physical deflection of the seismic mass in the sensing element due to an electrostatic force.
Thus, it provides full testing of the complete signal evaluation path including the micromachined
sensor structure and the evaluation ASIC.
The sensor is available in a standard SMD QFN package with a footprint of 4x4mm
2
and a
height of 1.2mm.
