MAX6514

www.DataSheet4U.com 19-3147; Rev 0; 1/04 Low-Cost, 2.7V to 5.5V Temperature Switches in a SOT23 General Description The MAX6514/MAX6515 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 +15°C and +35°C to +115°C in 10°C increments, and are accurate to ±1°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 MAX6514/MAX6515 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. The MAX6514/ MAX6515 can be used over a -35°C to +125°C range 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 MAX6514 has an active-high, push-pull output. The MAX6515 has 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.
