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.

type: int

description: |
|
|
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.
