STDS75
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: 125 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 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:
– SO8
– MSOP8 (TSSOP8)
SO8 (M)
MSOP8
(TSSOP8) (DS)
