MAX6516 Datasheet | Maxim Integrated

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 parator. 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 ponents 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 output proportional to temperature and are stable with any capacitive load up to 1000p F. The MAX6516- MAX6519 can be used over a range of -35°C to +125°C with a supply voltage of 2.7V to 5.5V. For applications sensing temperature down to -45°C, a supply voltage above 4.5V is required. The MAX6516 and MAX6518 have an active-high, push-pull output. The MAX6517 and MAX6519 have an active-low, open-drain output. These devices are available in a space-saving 5-pin SOT23 package and operate over the -55°C to +125°C temperature range.
