The TMP390 device is part of a family of ultra-low power, dual channel, resistor programmable temperature switches that enable protection and detection of system thermal events from –50°C to 130°C. The TMP390 offers independent overtemperature (hot) and undertemperature (cold) detection . The trip temperatures (TTRIP) and thermal hysteresis (THYST) options are programmed by two E96-series resistors (1% tolerance) on the SETA and SETB pins. Channel A resistors can range from 1.05 KΩ to 909 KΩ, representing one of 48 unique values. Channel B resistors can range from 10.5 KΩ to 909 KΩ
The value of the resistor to ground on SETA input sets the TTRIP threshold of Channel A. The value of the resistor to ground on SETB input sets the TTRIP threshold of Channel B, as well as the THYST options of 5°C, or 10°C for both channels, to prevent undesired digital output switching. When the SETB input is connected to ground, Channel A operates with 20°C hysteresis. Resistors accuracy has no impact to TTRIP accuracy.
To enable customer board-level manufacturing, the TMP390 supports a trip test function where the digital outputs are activated by exercising the SETA or SETB pin.
