TMP390/TMP390-Q1 Programmable Temperature Switches

Texas Instruments TMP390/TMP390-Q1 Resistor-Programmable Temperature Switches are ultra-low power, dual-channel, resistor-programmable temperature switches. These switches enable protection and detection of system thermal events from –50°C to 130°C. The TMP390/TMP390-Q1 offers independent over-temperature (hot) and under-temperature (cold) detection. The trip temperatures (T_TRIP) and thermal hysteresis (T_HYST) options are programmed by two E96-series (1%) standard decade value resistors on the SETA and SETB pins. Each resistor can range from 1.05KΩ to 909KΩ, representing one of 48 unique values.
