General Description
The BMM150 is a standalone geomagnetic sensor for consumer market applications. It allows
measurements of the magnetic field in three perpendicular axes. Based on Bosch’s proprietary
FlipCore technology, performance and features of BMM150 are carefully tuned and perfectly
match the demanding requirements of all 3-axis mobile applications such as electronic
compass, navigation or augmented reality.
An evaluation circuitry (ASIC) converts the output of the geomagnetic sensor to digital results
which can be read out over the industry standard digital interfaces (SPI and I2C).
Package and interfaces of the BMM150 have been designed to match a multitude of hardware
requirements. As the sensor features an ultra-small footprint and a flat package, it is ingeniously
suited for mobile applications. The wafer level chip scale package (WLCSP) with dimensions of
only 1.56 x 1.56 x 0.6 mm
3
ensures high flexibility in PCB placement.
The BMM150 offers ultra-low voltage operation (V
DD
voltage range from 1.62V to 3.6V, V
DDIO
voltage range 1.2V to 3.6V) and can be programmed to optimize functionality, performance and
power consumption in customer specific applications. The programmable interrupt engine gives
design flexibility to the developer.
The BMM150 senses the three axis of the terrestrial field in cell phones, handhelds, computer
peripherals, man-machine interfaces, virtual reality features and game controllers.
