  25. Description
  26. -----------
  27. The INA219 is a high-side current shunt and power monitor with an I2C
  28. interface. The INA219 monitors both shunt drop and supply voltage, with
  29. programmable conversion times and filtering.
  30. The INA220 is a high or low side current shunt and power monitor with an I2C
  31. interface. The INA220 monitors both shunt drop and supply voltage.
  32. The INA226 is a current shunt and power monitor with an I2C interface.
  33. The INA226 monitors both a shunt voltage drop and bus supply voltage.
  34. The INA230 is a high or low side current shunt and power monitor with an I2C
  35. interface. The INA230 monitors both a shunt voltage drop and bus supply voltage.
  36. The shunt value in micro-ohms can be set via platform data.
