1 Kernel driver ina3221 2 ===================== 3 4 Supported chips: 5 * Texas Instruments INA3221 6 Prefix: 'ina3221' 7 Addresses: I2C 0x40 - 0x43 8 Datasheet: Publicly available at the Texas Instruments website 9 http://www.ti.com/ 10 11 Author: Andrew F. Davis <afd@ti.com> 12 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. 20 21 Sysfs entries 22 ------------- 23 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 29 is above this value 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
