STS4xA from Sensirion is a series of digital automotive temperature sensor that comes in a DFN package. The series currently offers two versions: STS41A-AD1B and STS41A-AW1B. Both sensors feature an on-chip heater that enables the on-board diagnostics (OBD) and offers functionality and plausibility diagnosis instead of simple presence checks. In addition to that, the STS41A-AW1B model is capable of supplying optional wettable flank packaging to support automatic optical ins[ection (AOI).
“The expansion of our next-generation temperature sensor series means more opportunities for our customers to benefit from high precision and reliability in automotive applications. Our STS4xA temperature sensor builds on the established foundation of the STS4x sensor family, delivering a wide supply voltage range and low current consumption while maintaining top performance,” said Matthias Scharfe, product manager for humidity and temperature Sensors at Sensirion.
The STS4xA series is based on the company’s CMOSens Technology, the cost-effective device features an I2C interface for communication and supplies a wide supply voltage range. the compact sensor can be readily integrated into automotive temperature sensing applications. It also meets industry standards, such as 85C/85% RH accelerated life tests. Both the sensors come in a compact package measuring just 1.5×1.5×0.5 mm and can detect a wide range of temperatures from -40 to 125 °C with a typical temperature accuracy of 0.3 °C.
