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.
