STLM75
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: 125µA (typ)
■ No external components required
■ 2-Wire I²C/SMBus-compatible serial interface
– Supports bus time-out feature
– Selectable bus address allows connection
of up to eight devices on the bus
■ Wide power supply range-operating voltage
range: 2.7V to 5.5V
■ Conversion time is 150ms (max)
■ Programmable temperature threshold and
hysteresis set points
■ Pin- and software-compatible with LM75 (Drop-
in replacement)
■ Power-up defaults permit standalone operation
as a thermostat
■ Shutdown mode to minimize power
consumption
■ Output pin (open drain) can be configured for
interrupt or comparator/thermostat mode (Dual
Purpose Event Pin)
