In comparator mode (TM = 0), the ALERT pin becomes active when the temperature equals or exceeds the value in THIGH for a consecutive number of Fault Queue bits [F1:F0]. The ALERT pin remains active until the temperature falls below the indicated TLOW value for the same number of faults.
The difference between the two limits acts as a hysteresis on the comparator output, and a fault counter prevents false alerts as a result of system noise. The SMBus Alert response function is ignored in the comparator mode.
