| | 32 | ----------- |
| | 33 | |
| | 34 | The INA219 is a high-side current shunt and power monitor with an I2C |
| | 35 | interface. The INA219 monitors both shunt drop and supply voltage, with |
| | 36 | programmable conversion times and filtering. |
| | 37 | |
| | 38 | The INA220 is a high or low side current shunt and power monitor with an I2C |
| | 39 | interface. The INA220 monitors both shunt drop and supply voltage. |
| | 40 | |
| | 41 | The INA226 is a current shunt and power monitor with an I2C interface. |
| | 42 | The INA226 monitors both a shunt voltage drop and bus supply voltage. |
| | 43 | |
| | 44 | The INA230 is a high or low side current shunt and power monitor with an I2C |
| | 45 | interface. The INA230 monitors both a shunt voltage drop and bus supply voltage. |
| | 46 | |
| | 47 | The shunt value in micro-ohms can be set via platform data. |
