MAX6514：Low-Cost, 2.7V to 5.5V Temperature Switches in a SOT23

Industry's Most Accurate Temperature Switches Available in a SOT23 Package

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 +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 temperature thresholds (+35°C to +115°C), asserting when the temperature is above the threshold. The MAX6514/MAX6515 can be used over a -55°C to +125°C range with a supply voltage of 2.7V to 5.5V. 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.
