Temperature sensor withstands automotive use


An automotive-grade digital temperature sensor, the STS4xA from Sensirion, operates over a temperature vary of -40°C to +125°C with typical accuracy of ±0.3°C. The 16-bit sensor gives a large provide voltage vary of two.3 V to five.5 V and communicates through an I2C interface. An built-in on-chip heater allows superior onboard diagnostics, as a substitute of counting on easy presence checks.

With dimensions of simply 1.5×1.5×0.5 mm, the STS4xA’s 4-pin DFN package deal comes with elective wettable flanks to allow automated optical inspection. Due to its small dimension, the sensor will be simply built-in into a spread and automotive functions. Moreover, it meets AEC-Q100 reliability requirements, together with 85°C/85% RH accelerated life checks.

The STS4xA temperature sensor relies on Sensirion’s CMOSens expertise, which allows the fusion of the sensor factor and analysis electronics on a tiny CMOS silicon chip. Sensors are totally calibrated, eliminating the necessity for expensive and time-consuming calibration process.
