Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

The MAX6506 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).MAX6506 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 (T_AW) 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 +125°C. 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.

The MAX6506 are accurate to ±0.5°C (typ), ±5.5°C (max). Operating from a +2.5V to +5.5V supply,these low-cost devices typically consume 30A supply current and require no external components for setting trip points. The MAX6506 are available in a 6-pin SOT23 package.
