This chip is a 2-channel temperature monitor with dual PWM fan speed controller. It can monitor its own temperature and one external diode-connected transistor or two external diode-connected transistors. The following device attributes are implemented via sysfs: ====================== ==== =================================================== Attribute R/W Contents ====================== ==== =================================================== temp1_input R Temperature channel 1 input (0..150 C) temp2_input R Temperature channel 2 input (0..150 C) temp1_fault R Temperature channel 1 diode fault temp2_fault R Temperature channel 2 diode fault temp1_max RW Set THERM temperature for input 1 (in C, see datasheet) temp2_max RW Set THERM temperature for input 2 temp1_crit RW Set ALERT temperature for input 1 temp2_crit RW Set ALERT temperature for input 2 temp1_emergency RW Set OT temperature for input 1 (in C, see datasheet) temp2_emergency RW Set OT temperature for input 2 pwm1 RW Fan 1 target duty cycle (0..255) pwm2 RW Fan 2 target duty cycle (0..255) fan1_input R TACH1 fan tachometer input (in RPM) fan2_input R TACH2 fan tachometer input (in RPM) fan1_fault R Fan 1 fault fan2_fault R Fan 2 fault temp1_max_alarm R Alarm on THERM temperature on channel 1 temp2_max_alarm R Alarm on THERM temperature on channel 2 temp1_crit_alarm R Alarm on ALERT temperature on channel 1 temp2_crit_alarm R Alarm on ALERT temperature on channel 2 temp1_emergency_alarm R Alarm on OT temperature on channel 1 temp2_emergency_alarm R Alarm on OT temperature on channel 2 ====================== ==== =================================================== |
