STTS75

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: 75 µA (typ)

■ No external components required

■ 2-wire I2C/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 45 ms (typ)

■ Programmable temperature threshold and

hysteresis set points

■ Wide power supply range-operating voltage

range: 2.7 V to 5.5 V

■ Power saving one-shot temperature

measurement

■ 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:

–SO8

– MSOP8 (TSSOP8)
