  13 Description
  14 -----------
  15
  16 The Texas Instruments INA3221 monitors voltage, current, and power on the high
  17 side of up to three D.C. power supplies. The INA3221 monitors both shunt drop
  18 and supply voltage, with programmable conversion times and averaging, current
  19 and power are calculated host-side from these.
