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