Melexis offers modular tire pressure monitoring system
Melexis has unveiled its second generation solution for TPMS, which combines the MLX91801 Pressure Sensor and MLX72013 RF Transmitter. The TPMS module can be associated to the MLX71122 Multi-Channel RF Receiver in order to build a complete highly integrated solution, compliant with existing Remote Keyless Entry (RKE) systems.
Melexis utilizes time-of-flight technology for collision avoidance system
Chipmaker Melexis has licensed SoftKinectic's DepthSense range-sensing technology and plans to use it to implement a collision avoidance system. The versatile system will also be used for other automotive systems in the future.
Melexis integrated MEMs sensors handle more than just pressure
The MLX90807 and MLX90808 fully integrated, relative and absolute pressure sensor die are realized with CMOS technology combined with MEMS bulk micromachining. These monolithic solutions are both fully automotive qualified. Each consists of a silicon membrane with piezoresistors to transform the stress induced by pressure into an electrical signal. An analog signal chain interacting with a digital core, including programmable memory, allows full calibration on chip in order to achieve an optimized transfer function over the desired working pressure and temperature range.
Fully calibrated high accuracy MEMs infrared temperature sensor
Melexis has launched its 3rd generation of contactless MEMs infrared temperature sensors. The high accuracy of the newest member of the MLX90614 family makes it suitable for limitless applications in automotive, medical, industrial and consumer markets.
Melexis rolls second-generation Triaxis sensors
With a new generation of tri-axial sensors, Melexis addresses the needs of challenging applications in harsh automotive environments: EGR Valves, Turbo Wastegate Actuators, Electronic Throttle Body solutions, Steering angle, Suspension Height, Transmission Clutch; Shift and Fork position and Human Machine Interface are among the problems to be solved with the sensors.
The end of sensor-based BLDC control?
Vehicle manufacturers are increasingly appreciating the benefits of brushless DC (BLDC) motor control as a response to the challenges of making their fleet meet legal fuel economy regulations. Brushless DC motor control typically increases efficiency 20% to 30% compared to equivalent speed controlled DC solutions. Furthermore they may offer a weight and size reduction of up to 50% especially in high temperature environments like in the power train. Electric and hybrid vehicles generate less noise especially at lower speeds, making low noise BLDC motors the preferred solutions for pumps and fans that have been taken off the belt.
Rudi De Winter wants limping X-Fab to get up to speed
Past February, Rudi De Winter has been appointed co-CEO for semiconductor foundry X-Fab. Since his appointment took place shortly after X-Fab had released nine-month figures in red ink, speculations circulated that the move was aiming at a major course correction or a generational handover in the company. De Winter knows X-Fab very well: During the past 14 years he was CEO of fabless automotive chipmaker Melexis SA, a major customer of X-Fab.
Camera sensor brings high dynamic range to automotive applications
Melexis has developed a high dynamic range image sensor for use in a broad range of markets – automotive driver assistance and night vision applications applications in the first place. The camera sensor chip can also be used in security/surveillance cameras, fleet safety cameras, truck blind spot cameras, transportation/heavy vehicle cameras, and other outdoor and all weather cameras, the vendor said.
LIN slave chip connects switch modules, IO-extensions to LIN network
Melexis extends its family of smart LIN slave IC's with a new generation of reconfigurable LIN switch slave chips. The MLX80104 is designed to interface with any door, roof, seat, steering wheel, dashboard, HVAC, light control or similar switch module as well as for other application require an easy access via LIN.
