MAX6503UKN005+T

MAX6503UKN005+T low-cost, micropower fully integrated temperature switch which asserts a logic signal when their die temperature crosses a factory-programmed threshold. This device features two on-chip, temperature-dependent voltage references and a comparator. It has an active-low, open-drain output intended to interface with a microprocessor (µP) reset input. MAX6503 is offered with cold-temperature thresholds (-45°C to +15°C), asserting when the temperature is below the threshold. Application includes µP temperature monitoring in high-speed, computers, temperature control, temperature alarms, fan control.
