Melexis Makes a Splash with New Triphibian™ Pressure Sensor MLX90833 Featuring LIN Interface, Which Measuring Pressures Up to 70 Bar
MELEXIS introduces the MLX90833, a new pressure sensor with Triphibian™ technology, enabling robust measurement of both gas and liquid media from 2 to 70 bar, all within a compact SO16 package. This factory-calibrated device provides absolute pressure readings with a LIN digital output, simplifying integration for heat pump manufacturers.
The growing complexity of thermal management systems and the need for LIN
The increasing number of heating and cooling modes in heat pumps, particularly electric vehicles (EVs), is driving demand for standalone sensors with digital interfaces. These systems, which often include smart expansion valves, coolant pumps, and compressors, require efficient communication with the central control unit. Utilizing a digital bus like LIN reduces wiring complexity, improves system intelligence, and enables advanced diagnostics. This trend is especially prominent in Europe, where LIN is rapidly replacing legacy analog sensor outputs.
Simplified system design with Triphibian™ technology
Heat pump systems in battery electric vehicles (BEVs) can require five or more pressure and temperature sensors to ensure optimal performance. These sensors play a crucial role in regulating the high-voltage electric compressor and controlling the various expansion valves within the system. By integrating a LIN interface, the MLX90833 simplifies data transmission and system design compared to traditional analog or SENT connections.
Furthermore, the factory calibration of Melexis' Triphibian™ products significantly reduces development time and complexity for customers. Unlike non-Triphibian solutions, where customers must source separate sensing elements, signal conditioning integrated circuits (ICs), and invest in end-of-line calibration equipment, the MLX90833 comes fully calibrated and ready to integrate. This streamlines module design and lowers manufacturing costs.
Key features of the MLX90833:
Extended Pressure Range: MEMS sensor measuring pressures up to 70 bar, exceeding the limitations of traditional sensors.
Gas and liquid compatibility: Provides accurate readings in both media, simplifying system design.
LIN digital output: Enables seamless integration into bus-connected systems, reducing wiring complexity.
Enhanced Durability: Equipped with advanced protective mechanisms against overvoltage (above +40 V) and reverse voltage (below -40 V), making it suitable for demanding applications, including trucks.
"The MLX90833 is a game-changer for heat pump manufacturers," says Laurent Otte, Senior Product Line Director at Melexis. "Its ability to handle high pressures and both gas and liquid media, combined with the LIN interface, simplifies system design and improves overall efficiency."
The MLX90833 is a fully integrated solution, including a MEMS sensor, signal conditioning, and digital output drivers. It boasts high accuracy (± 0.5% FSO) and is developed as a Safety Element out of Context (SEooC) under ISO 26262, meeting the stringent safety requirements of modern EVs.
