4. Functional description
BMM150 is a triaxial standalone geomagnetic sensor (Sensing element and ASIC) in chip scale
wafer level package and can be operated via I2C or SPI as a slave device.
4.1 Power management
The BMM150 has two distinct power supply pins:
• VDD is the main power supply for all internal analog and digital functional blocks;
• VDDIO is a separate power supply pin, used for the supply of the digital interface as well as the
digital logic.
The device can be completely switched off (VDD = 0V) while keeping the VDDIO supply on (VDDIO >
0V) or vice versa.
It is absolutely prohibited to keep any interface at a logical high level when VDDIO is switched off.
Such a configuration will permanently damage the device (i.e. if VDDIO = 0 [SDI & SDO & SCK
& CSB] ≠ high).
The device contains a power on reset (POR) generator. It resets the logic part and the register
values of the concerned ASIC after powering-on VDD and VDDIO. Please note, that all application
specific settings which are not equal to the default settings (refer to register maps in chapter
5.2), must be re-set to its designated values after POR.
In case the I²C interface is used, a direct electrical connection between VDDIO supply and the PS
pin is recommended in order to ensure reliable protocol selection.
4.2 Power modes
The BMM150 features configurable power modes. The BMM150 magnetometer part has four
power modes:In the following chapters, power modes are described.
4.2.1 Power off mode
In Power off mode, VDD and/or VDDIO are unpowered and the device does not operate. When
only one of VDD or VDDIO is supplied, the magnetic sensor will still be in Power off mode. Power
on reset is performed after both VDD and VDDIO raised above their detection thresholds.
4.2.2 Suspend mode
Suspend mode is the default power mode of BMM150 after the chip is powered. When VDD and
VDDIO are turned on the POR (power on reset) circuits operate and the device’s registers are
initialized. After POR becomes inactive, a start up sequence is executed. In this sequence NVM
content is downloaded to shadow registers located in the device core. After the start up
sequence the device is put in the Suspend mode. In this mode only registers which store power
control bit information and SPI3 wire enable can be accessed by the user. No other registers
can be accessed in Suspend mode. All registers lose their content, except the control register
(0x4B). In particular, in this mode a Chip ID read (register 0x40) returns “0x00” (I²C) or high-Z
(SPI).
