| 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. | ||
