ti,ina237 (on i2c bus)

Vendor: Texas Instruments

Note

An implementation of a driver matching this compatible is available in drivers/sensor/ti/ina23x/ina237.c.

Description

TI INA237 Bidirectional Current and Power Monitor.
The <zephyr/dt-bindings/sensor/ina237.h> file should be included in the
DeviceTree and it provides macros that can be used for initializing the
configuration registers.

Name	Type	Details
alert-config	int	Diag alert register, default matches the power-on reset value
adc-mode	string	ADC channel conversion configuration. Default is the power-on reset value. Default value: Temperature, bus, and shunt voltage continuous Legal values: 'Shutdown single shot', 'Bus Voltage single shot', 'Shunt Voltage single shot', 'Bus and Shunt Voltage single shot', 'Temperature Single shot', 'Temperature and bus voltage single shot', 'Temperature and shunt voltage single shot', 'Temperature, bus, and shunt voltage single shot', 'Shutdown continuous', 'Bus voltage continuous', 'Shunt voltage continuous', 'Bus and shunt voltage continuous', 'Temperature continuous', 'Temperature and bus voltage continuous', 'Temperature and shunt voltage continuous', 'Temperature, bus, and shunt voltage continuous'
vbus-conversion-time-us	int	Vbus conversion time in microseconds. Default is the power-on reset value. Default value: 1052 Legal values: 50, 84, 150, 280, 540, 1052, 2074, 4120
vshunt-conversion-time-us	int	Vshunt conversion time in microseconds. Default is the power-on reset value. Default value: 1052 Legal values: 50, 84, 150, 280, 540, 1052, 2074, 4120
temp-conversion-time-us	int	Temperature conversion time in microseconds. Default is the power-on reset value. Default value: 1052 Legal values: 50, 84, 150, 280, 540, 1052, 2074, 4120
avg-count	int	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
high-precision	boolean	Enable high precision mode (4x the resolution).
current-lsb-microamps	int	This value should be selected so that measurement resolution is maximized, that is: current-lsb(A) = maximum expected current(A) / 2^15 (sensor has 15 bits). For example, if maximum expected current is 15A: current-lsb(A) = 15A / 2^15 ~= 457uA Rounded values may be used for convenience, e.g. 500uA/LSB or 1mA/LSB while keeping a good measurement resolution. The units are in uA/LSB so that low maximum currents can be measured with enough resolution. This property is required.
rshunt-micro-ohms	int	Shunt resistor value in microOhms This property is required.
alert-gpios	phandle-array	Alert pin
friendly-name	string	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	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	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.
