Digital temperature sensor and thermal watchdog
Features
■ Measures temperatures from -55°C to +125°C (-67°Fto+257°F)
- ±2°C accuracy from -25°C to +100°C
(max)
■ Low operating current: 125 uA (typ)
■ No external components required
■ 2-wire I C/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 150 ms (max)
■ Programmable temperature threshold and hysteresis set points
■ Wide power supply range-operating voltage range: 2.7 V to 5.5 V
■ Pin- and software-compatible with DS75 (drop-in replacement)
■ Power-up defaults permit standalone 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)
■ Packages:
- S08
- MSOP8 (TSSOP8)
