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.
