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.
24 in[123]_input Bus voltage(mV) channels
25 curr[123]_input Current(mA) measurement channels
26 shunt[123]_resistor Shunt resistance(uOhm) channels
27 curr[123]_crit Critical alert current(mA) setting, activates the
28 corresponding alarm when the respective current
30 curr[123]_crit_alarm Critical alert current limit exceeded
31 curr[123]_max Warning alert current(mA) setting, activates the
32 corresponding alarm when the respective current
33 average is above this value.
34 curr[123]_max_alarm Warning alert current limit exceeded
35 in[456]_input Shunt voltage(uV) for channels 1, 2, and 3 respectively
