MAX6516

19-3007; Rev 1; 2/11 MAX6516–MAX6519 Low-Cost, 2.7V to 5.5V, Analog Temperature Sensor Switches in a SOT23 General Description The MAX6516–MAX6519 low-cost, fully integrated temperature switches assert a logic signal when their die temperature crosses a factory-programmed threshold. Operating from a 2.7V to 5.5V supply, these devices feature a fixed voltage reference, an analog temperature sensor, and a comparator. They are available with factory-trimmed temperature trip thresholds from -45°C to +115°C in 10°C increments, and are accurate to ±0.5°C (typ). These devices require no external components and typically consume 22µA of supply current. Hysteresis is pin selectable at 2°C or 10°C. The MAX6516–MAX6519 are offered with hot-temperature thresholds (+35°C to +115°C), asserting when the temperature is above the threshold, or with cold-temperature thresholds (-45°C to +15°C), asserting when the temperature is below the threshold. These devices provide an analog ou...
