Dual Trip SOT Temperature Switches
MAX6505–MAX6508
General Description
The MAX6505–MAX6508 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 5°C increments.
The MAX6505/MAX6506 have an ALARM output that asserts when the temperature is above the factory-programmed thresholds (available from -40°C to +125°C). 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 (ΔTAW) is pin selectable to +5°C, +10°C, +20°C, or +30°C. 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 -40°C to +12.
