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: 125 µA (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: 2.7 V to 5.5 V

■ Conversion time is 150 ms (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)

■ Packages:

–SO8

– MSOP8 (TSSOP8)

SO8 (M)

MSOP8

(TSSOP8) (DS)
