Françoise is co-founder and chairwoman of the board of Melexis. She tells Caroline Hayes how the Belgian company has grown from a startup specialising in custom asics to a company with a portfolio of sensor, driver and transceiver ICs and offices around the world, Founded in 1989 in Belgium, Melexis has grown to employ more than 2,000 people in 12 ...

ScioSense has launched a two-channel time-to-digital converter for lidar distance measurement. LTDC-X3, as it will be known, offers single-shot resolution of up to 20ps(rms). The chip has one ‘start’ input and two ‘stop’ inputs, and calculates the time differences between the start channel and the stop channels. “In typical lidar designs, the start will be triggered by the laser trigger, ...

Melexis has cone up with Arcminaxis –  a magnetic technology for affordable, high-precision position sensing in robotic joints. The MLX90384, the first product incorporating Arcminaxis, reduces the complexity and effort involved in assembling robotic joints. It comes with a magnet and a SW package to calibrate and operate the system. Historically, within many robotic designs, the highest-performance sensors have typically ...

ADI has announced an IC that can not only measure the angle of a nearby rotating magnet, but can count up to 46 complete turns even when the chip has no power. For those who like puzzles, look away for a couple of minutes to work out the mechanism for yourself, as it is going to be explained in the ...

Novosense Microelectronics has announced a series of automotive-grade IC current sensors with 5kVrms isolation (UL) between the current path and sensing circuitry. Certification is AEC-Q100 Grade 0. The NSM211x series is fast, with a 1MHz -3dB bandwidth and 400ns response time. It comes in three packaging options: SOP8, SOW16 and SOW10. Read our full Electronica 2024 coverage » Only the ...

STMicroelectronics is aiming at healthcare wearables with an IC that senses bio-potentials and acceleration, and includes an AI processor and a finite state-machine for pedometer, step detection and step counting. “The machine-learning core and finite state machine enable product designers to implement simple decision trees for neural processing on the chip,” according to the company. “ST1VAFE3BX provides opportunities to extend ...

Melexis has put two of its MLX90423 three-axis magnetic flux sensors in the same package along with a magnetic wake-up sensor to detect linear and rotary movement in high-reliability applications such as brake and accelerator pedal position sensing in vehicles Called MLX90424, it can be powered directly from 12V without a regulator and measures linear displacement up to 30mm without ...

Sensirion has introduced a less accurate version of its 1.5 x 1.5 x 0.5mm STS4x temperature family. STS4L has typical errors within ±0.4°C between 0 and 60°C. Operation is over -40 to 125°C and 1.08 to 3.6V, consuming an average of 400nA at 1Hz reading rate, and idling at 80nA typ (25°C, 1µA max, 3.4µA max across temperature). Measurement peaks ...

Renesas has introduced a four-channel IO-Link master for the industrial IO-Link bus, and a dual-channel resistive sensor signal conditioner. “IO-Link has become increasingly popular in recent years due to its ability to provide real-time data and diagnostics, and its compatibility with existing systems,” said Renesas, adding that it also offers remote configuration and monitoring. CCE4511 is the four-channel IO-Link master, ...

Infineon has announced a pair of fingerprint sensors that include the sensing matrix, processing silicon and related software for the host processor. They are very similar, but CYFP10020A00 works over -40 to +85°C, while CYFP10020S00 operates up to +105°C. As well as fingerprint reading, finger touch-down and lift-off are detected, and the sensors can act as a miniature track-pad by ...
