Last week Belgian fabless chip company Melexis announced a unique inductive sensing IC that includes a tiny transformer, drive circuit and sense circuit, so Electronics Weekly decided to have a closer look. No permanent magnet, external or internal, is needed, and external magnetic fields are rejected. MLX92442 only requires a nearby electrically conductive object for triggering. It comes in either ...

There's TSMC expecting industry growth, an old story of state investment in R&D, Google planning a $1bn UK data centre for AI, a MEMS sensor using Triphibian technology, and Intel back on top of the semiconductor revenue charts...

Melexis claims that its Hall-effect sensor, the MLX90394 Triaxis micropower magnetometer, balances the design trade-off between low noise, current consumption and cost. With on-the-fly selectable modes and advanced configurability, it aims to enable high reuse and fast time to market. This contactless solution is suitable for rotary, linear and 3D joystick control in gaming and industrial peripherals. Replacing mechanical solutions, ...

Melexis has added the MLX91231, a shunt-based sensing automotive current sensor for IVT (current, voltage, and temperature) and a digital microcontroller (MCU). The sensor is designed to measure low voltage electronics in vehicle safety systems. It has sensitivity drift error over temperature and lifetime below ±0.25% and a 1.5μV input referred offset drift error over the same conditions. Integrating the ...

Melexis is claiming 1% accuracy over temperature and life for its latest galvanically-isolated Hall effect current sensor. “MLX91230 guarantees this accuracy not only for thermal drift but also lifetime drift and linearity errors,” according to the company. The 8pin SOIC device is AEC-Q100 and ASIL compliant, supporting system integration up to ISO 26262 ASIL D functional safety requirements. Current measurement ...

Caroline Hayes visited the Melexis Innovation Lab in Bevaix, Switzerland, to discover how the company is looking for growth and innovation beyond the automotive market. There are lots of theories around on how to engender creativity. For some, necessity is the mother of invention, resulting in the plough and the loom. For others, creative thinking needs to be nurtured. It ...

Increasing interest – and reliance on – data-based healthcare means device manufacturers are looking for more parameters to integrate into wearable devices, says Dr Joris Roels of Melexis. An increasing proportion of the population is becoming health conscious, and is expecting technology to assist them to get up-to-date information on their current physical condition. There is a clear need to ...

Melexis has unveiled what it claims is “the most accurate automotive pressure sensor ever made”. Intended for automotive engine management, the mems-based devices measure absolute pressure across 1 to 4bar. MLX90824 delivers a SENT protocol digital output MLX90822 has an analogue voltage output voltage “An accuracy of +/-0.5% of full scale is maintained over the course of the sensor’s working ...

A LIN pre-driver IC for relay DC motors from Melexis  includes 48 KB of memory (16 KB ROM for the included LIN protocol and 32 KB Flash for the application software. The MLX81160 is the latest addition to the company’s Gen3 family of compatible embedded motor drivers. By leveraging high-voltage SOI technology, this LIN-based pre-driver exhibits operational robustness for 12 ...

Melexis has introduced the MLX90377 single- and dual-die (fully redundant) Triaxis position sensor for automotive and industrial applications together with a new PCB-less package for position sensors. The MLX90377 is a magnetic rotary and linear position sensor IC, which builds on the success of the MLX90371 and MLX90372 Triaxis sensors. Based on the Triaxis Hall magnetic front-end, it integrates an ...
