MAX6515UKP015+T General Description

The MAX6514/MAX6515 low-cost, fully integrated temper-ature switches assert a logic signal when their die tem-perature crosses a factory-programmed threshold.Operating from a 2.7V to 5.5V supply, these devices fea-ture a fixed voltage reference, an analog temperaturesensor, and a comparator. They are available with facto-ry-trimmed temperature trip thresholds from -45°C to+15°C and +35°C to +115°C in 10°C increments, and areaccurate to ±1°C (typ). These devices require no externalcomponents and typically consume 22µA of supply cur-rent. Hysteresis is pin selectable at 2°C or 10°C.The MAX6514/MAX6515 are offered with hot-tempera-ture thresholds (+35°C to +115°C), asserting when thetemperature is above the threshold or with cold-temper-ature thresholds (-45°C to +15°C), asserting when thetemperature is below the threshold. The MAX6514/MAX6515 can be used over a -35°C to +125°C rangewith a supply voltage of 2.7V to 5.5V. For applicationssensing temperature down to -45°C, a supply voltageabove 4.5V is required.The MAX6514 has an active-high, push-pull output. TheMAX6515 has an active-low, open-drain output. Thesedevices are available in a space-saving 5-pin SOT23package and operate over the -55°C to +125°C tem-perature range.
