Digital temperature sensor and thermal watchdog
Features ■ Measures temperatures from -55°C to +125°C (-67°F to +257°F) - ±2°C Accuracy from -25°C to +100°C (max) ■ Low operating current: 75pA (typ) ■ No external components required ■ 2-wire l2C/SMBus-compatible serial interface - Selectable serial bus address allows connection of up to eight devices on the same bus ■ Thermometer resolution is user-configurable from 9 (Default) to 12 bits (0.5°C to 0.0625°C) ■ 9-bit conversion time is 45ms (typ) ■ Programmable temperature threshold and hysteresis set points ■ Wide power supply range-operating voltage range: 2.7V to 5.5V ■ Power saving one-shot temperature measurement ■ Power up defaults permit stand-alone operation as thermostat ■ Shutdown mode to minimize power consumption ■ Separate open drain output pin operates as an interrupt or comparator/thermostat output (dual purpose event pin)
