Description |
|
----------- |
|
|
|
The INA219 is a high-side current shunt and power monitor with an I2C |
|
interface. The INA219 monitors both shunt drop and supply voltage, with |
|
programmable conversion times and filtering. |
|
|
|
The INA220 is a high or low side current shunt and power monitor with an I2C |
|
interface. The INA220 monitors both shunt drop and supply voltage. |
|
|
|
The INA226 is a current shunt and power monitor with an I2C interface. |
|
The INA226 monitors both a shunt voltage drop and bus supply voltage. |
|
|
|
The INA230 is a high or low side current shunt and power monitor with an I2C |
|
interface. The INA230 monitors both a shunt voltage drop and bus supply voltage. |
|
|
|
The shunt value in micro-ohms can be set via platform data or device tree. |
|
Please refer to the Documentation/devicetree/bindings/i2c/ina2xx.txt for bindings |
|
if the device tree is used.
