ZHCSAV1A April 2013 – September 2019 TMP108
PRODUCTION DATA.
The TMP108 uses temperature watchdog flags in the configuration register that indicate the result of comparing the device temperature at the end of every conversion to the values stored in the temperature limit registers (THIGH and TLOW). If the temperature of the TMP108 exceeds the value in the THIGH register, then the flag-high bit (FH) in the configuration register is set to 1. If the temperature falls below the value in the TLOW register, then the flag-low bit (FL) is set to 1. If both flag bits remain 0, then the temperature is within the temperature range set by the temperature limit registers. In interrupt mode, when any of the flags is set by an under- or overtemperature event, the SMBus ALERT Response only clears the pin and not the flags. Reading the configuration register clears both the flags and the pin.
