Features & Applications

For over a decade, Melexis customers in the automotive electronics market have inspired the company to create, manufacture and deliver advanced Mixed Signal semiconductors, sensor ICs, and programmable sensor IC systems. Through the stringent quality expectations, hostile operating conditions and aggressive economic targets demanded by our automotive customers, Melexis has developed the capability to produce world class, value driven, innovative products. Industry leading innovation in programmable sensors, sensor interface devices and microcontrollers provide our customers with competitive advantage in system cost, capability and flexibility.

The MLX90614 is an Infra Red thermometer for non contact temperature measurements. Both the IR sensitive thermopile detector chip and the signal conditioning ASIC are integrated in the same TO-39 can. Integrated into the MLX90614 are a low noise amplifier, 17-bit ADC and powerful DSP unit thus achieving high accuracy and resolution of the thermometer. The thermometer comes factory calibrated with a digital SMBus output giving full access to the measured temperature in the complete temperature range(s) with a resolution of 0.02 °C. The user can configure the digital output to be PWM. As a standard, the 10-bit PWM is configured to continuously transmit the measured temperature in range of -20 °C to 120 °C, with an output resolution of 0.14 °C.

Some of the product key applications are window condensations sensing and prediction, tire pressure monitoring systems, comfort sensing, misting and fogging detection and prevention, seat occupant detection, temperature measurement, room temperature sensing, perishable goods temperature tracking, process monitoring, fever measurement, and diagnostic systems.
