This device is available in SOIC-8 and VSSOP-8 packages, and requires no external • Overtemperature ALERT Pin with Programmable components to sense the temperature. The TMP75B Trip Values is capable of reading temperatures with a resolution • Shutdown Mode for Battery Power Saving of 0.0625°C and is specified over a temperature • One-Shot Conversion Mode for Custom Update range of –55°C to +125°C. Rates The TMP75B features SMBus and two-wire interface • Operating Temperature Range: –55°C to +125°C compatibility, and allows up to eight devices on the same bus with the SMBus overtemperature alert • Operating Supply Range: 1.4 V to 3.6 V function. The programmable temperature limits and • Quiescent Current: the ALERT pin allow the sensor to operate as a – 45 μA Active (typ) stand-alone thermostat, or an overtemperature alarm – 0.3 μA Shutdown (typ) for power throttling or system shutdown. • Accuracy: The factory-calibrated temperature accuracy and the noise-immune digital interface make the TMP75B the – ±0.5°C (typ) from –20°C to +85°C preferred solution for temperature compensation of – ±1°C (typ) from –55°C to +125°C other sensors and electronic components, without the • Resolution: 12 Bits (0.0625°C) need for additional system-level calibration or • Packages: SOIC-8 and VSSOP-8 elaborate board layout for distributed temperature sensing. 2 Applications The TMP75B is ideal for thermal management and protection of a variety of consumer, computer, • Server and Computer Thermal Management communication, industrial, and environmental • Telecommunication Equipment applications. • Office Machines • Video Game Consoles Device Information(1) • Set-Top Boxes DEVICE NAME PACKAGE BODY SIZE (NOM) SOIC (8) 4.90 mm × 3.90 mm • Power Supply and Battery Thermal Protection TMP75B VSSOP (8) 3.00 mm × 3.00 mm • Thermostat Control (1) For all available packages, see the package option addendum • Environmental Monitoring and HVAC at the end of the datasheet. • Electrical Motor Driver Thermal Protection Temperature Accuracy (Error) vs Ambient Simplified Schematic Temperature 1 An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.
