21 | ||
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. |
