20 | ----------- | ||
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. | ||
