Ultra-compact digital temperature sensor with precise output

21-02-2020 | TE Connectivity | Test & Measurement

TE Connectivity has designed the TSYS03, a new digital temperature sensor with an ultra-compact design, precise multi-channel digital output and low power consumption.


The device is offered in two different sizes – TDFN8 2.5mm x 2.5mm and ultra-small XDFN6 1.5mm x 1.5mm – providing a great choice of integrations to any application with space constraints. The products small size allows lower thermal response time, which equates to fast temperature readings, while its enhanced ASIC design and decreased package size provides for an outstanding price-to-performance ratio.


“Providing sensor solutions that meet the needs of our customers is at the forefront of everything we do at TE Connectivity,” said Noel Burke, product manager of TE sensors business. “The development of the new TSYS03 sensor further enhances our position as a leader in the sensor industry and is intended for use in products across an array of sectors that require digital output and a miniature footprint including industrial, medical, automotive and consumer.”


The sensor provides a digital output enabling the I2C communication bus to be configured giving OEMs the capability to add a secondary or more I2C addresses. Furthermore, the device has an enlarged supply voltage range of 2.4V to 5.5V providing an extensive range of application possibilities from automotive to any other battery-driven devices. Due to its low current consumption (stand-by <0.3µA), the device can be employed in battery applications for years with no recharging or battery replacement.
