Description

.. code-block:: none

   TI INA226 Bidirectional Current and Power Monitor.
   The <zephyr/dt-bindings/sensor/ina226.h> file should be included in the
   DeviceTree as it provides macros that can be used for initializing the
   configuration registers.

.. tabs::

   .. group-tab:: Node specific properties

      Properties not inherited from the base binding file.

      .. list-table::
         :widths: 1 1 4
         :header-rows: 1

         * - Name
           - Type
           - Details

         * - ``friendly-name``
           - ``string``
           - .. code-block:: none

                Human readable string describing the sensor. It can be used to
                distinguish multiple instances of the same model (e.g., lid accelerometer
                vs. base accelerometer in a laptop) to a host operating system.

                This property is defined in the Generic Sensor Property Usages of the HID
                Usage Tables specification
                (https://usb.org/sites/default/files/hut1_3_0.pdf, section 22.5).



         * - ``supply-gpios``
           - ``phandle-array``
           - .. code-block:: none

                GPIO specifier that controls power to the device.

                This property should be provided when the device has a dedicated
                switch that controls power to the device.  The supply state is
                entirely the responsibility of the device driver.

                Contrast with vin-supply.



         * - ``vin-supply``
           - ``phandle``
           - .. code-block:: none

                Reference to the regulator that controls power to the device.
                The referenced devicetree node must have a regulator compatible.

                This property should be provided when device power is supplied
                by a shared regulator.  The supply state is dependent on the
                request status of all devices fed by the regulator.

                Contrast with supply-gpios.  If both properties are provided
                then the regulator must be requested before the supply GPIOS is
                set to an active state, and the supply GPIOS must be set to an
                inactive state before releasing the regulator.



         * - ``avg-count``
           - ``int``
           - .. code-block:: none

                Number of samples to average (applies to all inputs).
                Default is the power-on reset value.



             Default value: ``1``

             Legal values: ``1``, ``4``, ``16``, ``64``, ``128``, ``256``, ``512``, ``1024``

         * - ``vbus-conversion-time-us``
           - ``int``
           - .. code-block:: none

                Vbus conversion time in microseconds.
                Default is the power-on reset value.



             Default value: ``1100``

             Legal values: ``140``, ``204``, ``332``, ``588``, ``1100``, ``2116``, ``4156``, ``8244``

         * - ``vshunt-conversion-time-us``
           - ``int``
           - .. code-block:: none

                Vshunt conversion time in microseconds.
                Default is the power-on reset value.



             Default value: ``1100``

             Legal values: ``140``, ``204``, ``332``, ``588``, ``1100``, ``2116``, ``4156``, ``8244``

         * - ``operating-mode``
           - ``string``
           - .. code-block:: none

                Selects mode of operation.
                Default is the power-on reset value.



             Default value: ``Shunt and Bus, Continuous``

             Legal values: ``'Power-Down (or Shutdown)'``, ``'Shunt Voltage, Triggered'``, ``'Bus Voltage, Triggered'``, ``'Shunt and Bus, Triggered'``, ``'Power-Down (or Shutdown)'``, ``'Shunt Voltage, Continuous'``, ``'Bus Voltage, Continuous'``, ``'Shunt and Bus, Continuous'``

         * - ``current-lsb-microamps``
           - ``int``
           - .. code-block:: none

                Current LSB value in microAmpere.
                This value gives the measurement resolution for current measurement.
                Formula: current-lsb [μA] = maximum expected current [μA] / 2^15
                Higher resolution means lower range of current measurement, vice versa.

                For example, if maximum expected current is 15 [A]:
                  then, current-lsb [μA] = 15000000 [μA] / 2^15 ~= 457.763 [μA].

                Note: rounded values may be used for convenience, e.g. 500uA/LSB.



             This property is **required**.

         * - ``rshunt-micro-ohms``
           - ``int``
           - .. code-block:: none

                Shunt resistor value in micro-ohms.



             This property is **required**.

                wake up the system.

                Wake up capable devices are disabled (interruptions will not wake up
                the system) by default but they can be enabled at runtime if necessary.
