The MAX6505MAX6508 temperature switches have dual logic outputs that assert when the die temperature crosses their trip thresholds. Trip thresholds are factory programmed to convenient temperatures in 5C increments. The MAX6505/MAX6506 have an ALARM output that asserts when the temperature is above the factory-programmed thresholds (available from -40C to +125C). They also have a WARN output that asserts when the temperature is several degrees below the ALARM threshold. The difference between the ALARM and WARN thresholds (TAW) is pin selectable to +5C, +10C, +20C, or +30C. The MAX6505's logic outputs are open drain, while the MAX6506's logic outputs are push-pull. The MAX6507 has open-drain outputs (OVER, OK), and the MAX6508 has push-pull outputs (OVER, OK), each with two factory-programmed threshold temperatures (TOVER and TUNDER) in the wide range of -40C to +125C. The overtemperature output asserts when the temperature is above TOVER. When the temperature is in the desired window (less than TOVER and greater than TUNDER), OK (OK) asserts.
