The operating 24supply voltage is from 3.0V to 3.6V. Resistance cancellation compensates 25for high series resistance in circuit-board traces and the external thermal 26diode, while beta compensation corrects for temperature-measurement 27errors due to low-beta sensing transistors. 28 29 30Sysfs entries 31------------- 32 33=================== == ======================================================= 34temp[1-4]_enable RW Temperature enable/disable 35 Set to 0 to enable channel, 0 to disable 36temp[1-4]_input RO Temperature input 37temp[2-4]_fault RO Fault indicator for remote channels 38temp[1-4]_max RW Maximum temperature 39temp[1-4]_max_alarm RW Maximum temperature alarm 40temp[1-4]_min RW Minimum temperature.
