Davis <afd@ti.com> 12 13Description 14----------- 15 16The Texas Instruments INA3221 monitors voltage, current, and power on the high 17side of up to three D.C. power supplies. The INA3221 monitors both shunt drop 18and supply voltage, with programmable conversion times and averaging, current 19and power are calculated host-side from these. 20 21Sysfs entries 22------------- 23 24in[123]_input Bus voltage(mV) channels 25curr[123]_input Current(mA) measurement channels 26shunt[123]_resistor Shunt resistance(uOhm) channels 27curr[123]_crit Critical alert current(mA) setting, activates the 28 corresponding alarm when the respective current 29 is above this value 30curr[123]_crit_alarm Critical alert current limit exceeded 31curr[123]_max Warning alert current(mA) setting, activates the 32 corresponding alarm when the respective current 33 average is above this value. 34curr[123]_max_alarm Warning alert current limit exceeded 35in[456]_input Shunt voltage(uV) for channels 1, 2, and 3 respectively 36
