| 22 | The INA219 is a high-side current shunt and power monitor with an I2C | |
| 23 | interface. The INA219 monitors both shunt drop and supply voltage, with | |
| 24 | programmable conversion times and filtering. | |
| 25 | ||
| 26 | The INA226 is a current shunt and power monitor with an I2C interface. | |
| 27 | The INA226 monitors both a shunt voltage drop and bus supply voltage. | |
| 28 | ||
| 29 | The shunt value in micro-ohms can be set via platform data. |
