MAXIM MAX6519UKP105+

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 output proportional to temperature and are stable with any capacitive load up to 1000pF. 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.
