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.
