PRODUCTION DATA. TMP275-Q1 SBOS760A – NOVEMBER 2015 – REVISED JANUARY 2016 TMP275-Q1 Automotive Grade ±0.5°C Temperature Sensor with I2C and SMBus Interface in Industry-Standard LM75 Form Factor and Pinout 1 1 Features 1 • AEC-Q100 Qualified with: – Temperature Grade 1: –40°C to +125°C Ambient Operation Temperature Range – HBM ESD Classification Level 2 – CDM ESD Classification Level C6 • High Accuracy: – ±0.5°C (Maximum) from −20°C to +100°C – ±1°C (Maximum) from −40°C to +125°C • Low Quiescent Current: – 50 μA (Typical) – 0.1 μA (Standby) • Resolution: 9 to 12 Bits, User-Selectable • Digital Output: SMBus™, Two-Wire, and I2C Interface Compatibility • 8 I2C, SMBus Addresses • Wide Supply Range: 2.7 V to 5.5 V • Small 8-Pin VSSOP and SOIC Packages • No Specified Power-Up Sequence Required, Two- Wire Bus Pullups Can Be Enabled Before V+ 2 Applications • Climate Controls • Infotainment Processor Management • Airflow Sensors • Battery Control Units • Engine Control Units • UREA Sensors • Water Pumps • HID Lamps • Airbag Control Units Simplified Schematic 3 Description The TMP275-Q1 is a ±0.5°C, accurate integrated digital temperature sensor with a 12-bit, analog-to- digital converter (ADC) that can operate on a supply voltage as low as 2.7 V and is pin- and register- compatible with the Texas Instruments' LM75, TMP75, TMP75B, and TMP175 devices. The TMP275-Q1 device is available in 8-pin SOIC and VSSOP packages and requires no external components to sense temperature. The device is capable of reading temperatures with a maximum resolution of 0.0625°C (12 bits) and as low as 0.5°C (9 bits), thus allowing the user to maximize efficiency by programming for higher resolution or faster conversion time. The device is specified over the temperature range of –40°C to +125°C. The TMP275-Q1 device features SMBus and two- wire interface compatibility, and allows up to eight devices on the same bus with the SMBus overtemperature alert function. The factory-calibrated temperature accuracy and the noise-immune digital interface make the TMP275-Q1 the preferred solution for temperature compensation of other sensors and electronic components, without the need for additional system-level calibration or elaborate board layout for distributed temperature sensing.
