MAX6508UT0A32-T

The MAX6505–MAX6508UT0A32+T 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 (active-low OVER, OK), and the MAX6508UT0A32+T has push-pull outputs (OVER, active-low 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 (active-low OK) asserts. The MAX6505–MAX6508UT0A32+T 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 30μA supply current and require no external components for setting trip points. The MAX6505–MAX6508UT0A32+T are available in a 6-pin SOT23 package.
