MAX6508 Datasheet | Maxim Integrated

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 +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 MAX6505- MAX6508 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 ponents for setting trip points. The MAX6505- MAX6508 are available in a 6-pin SOT23 package. ________________________Applications µP Temperature Monitoring in High-Speed puters Temperature Control Temperature Alarms Fan Control Typical Operating Circuits appear at end of data sheet.
