STDS75
Digital temperature sensor and thermal watchdog
Features
â Measures temperatures from â55°C to +125°C
(â67°F to +257°F)
â ±2°C Accuracy from â25°C to +100°C
(max)
â Low operating current: 125µA (typ)
â No external components required
â 2-wire I2C/SMBus-compatible serial interface
â Selectable serial bus address allows
connection of up to eight devices on the
same bus
â Thermometer resolution is user-configurable
from 9 (Default) to 12 bits (0.5°C to 0.0625°C)
â 9-bit conversion time is 150ms (max)
â Programmable temperature threshold and
hysteresis set points
â Wide power supply range-operating voltage
range: 2.7V to 5.5V
â Pin- and software-compatible with DS75 (drop-
in replacement)
â Power up defaults permit stand-alone
operation as thermostat
â Shutdown mode to minimize power
consumption
â Separate open drain output pin operates as an
interrupt or comparator/thermostat output (dual
purpose event pin)
â Packages:
â SO8
â MSOP8 (TSSOP8)(a)
SO8 (M)
MSOP8
(TSSOP8) (DS)
