Danisense, the current sense transducer specialist, is introducing its ‘Online Calibration Portal’ to offer brand agnostic calibration services for current transducers. Via the new personal online portal, which will be available in Mid-May 2025 on Danisense’s website www.danisense.com, customers can book their brand agnostic calibrations for current transducers to be performed in the ISO 17025 accredited Calibration Lab from Danisense, ...

Vishay has released a digital ambient light sensor in a 4.38 x 1.45 x 0.6mm package, with AEC-Q100 qualification for automotive use. VEML4031X00, as it will be known, has a visible light spectral sensitivity designed to match the human eye, and also includes an ambient infra-red sensor for light source differentiation. “With an ambient light range from 0 to 172 ...

Asahi Kasei Microdevices  (AKM) and Silicon Austria Labs GmbH (SAL) have completed a joint proof of concept for integrating a current sensor into a power module to be used in automotive applications such as traction inverters and DC-DC converters. The technology enables energy efficiency, as well as compact and lightweight design for high current applications using  SiC power devices. Market ...

LEM had introduced two fast precision high current sensors for ac, dc and pulsed currents: a 2MHz 1,500A type and 1ns 1,000A type. IN 1500-S is for measuring up to 1.5kA across a 2MHz (±3dB) bandwidth and -40 to +50°C temperature – which is less than the -40°C and +85°C that the rest of the IN family is rated across. ...

Infineon has announced a series of three pin ASIL-B-compliant magnetic switch ICs for automotive use. “Developed in accordance with ISO 26262, the TLE4960x switches integrate diagnostic functions to support functional safety applications,” according to Infineon. “In addition, the devices are AEC-Q100 compliant and qualified to Grade 0, ensuring robust performance in harsh environments.” With the base part number TLE4960x-xM-S2, they ...

Hamamatsu Photonics has launched a series of avalanche photo diodes that work across 320 to 1,000nm. Sensitivity peaks at 750nm. Called the S17353 series, they share a typical sensitivity of 0.44A/W at 650nm, and the six models vary in photosensitive diameter from 0.2 to 5mm. The smallest has a capacitance of 1pF and can be esxpected to work at 1GHz ...

Bosch has signed Arrow Electronics to distributes its automotive semiconductor components in EMEA, building on an existing agreement for North America. The agreement extends to Bosch‘s MEMS sensors, asics and SiC chips.  “We are convinced that automotive manufacturers and suppliers in Europe will benefit from our co-operation,” said Philipp Schäfer, senior vice president, sales at Bosch Mobility Electronics. Two generations ...

Melexis has created a 32 x 24 pixel far-infra-red sensor array that can photograph the temperature of objects at between -40 and +260°C. Dubbed MLX90642, it comes in a 9.3mm diameter four-lead TO39 through-hole package in two versions: a squat (5.7mm tall) 110° x 75° wide-view type (BCA suffix) and a taller (11.9mm) 45° x 35° narrow-view version (BCB). The ...

Diodes is aiming at contactless rotary motion and proximity detection with a 3D Hall-effect magnetic field sensor. Automotive applications are envisaged, include infotainment rotary and push selectors, gear shifts, door handles and powered seat adjusters, it said. AH4930Q, as it will be known, comes in a ~3 x 3 x 1.5mm SOT-26 package and includes three sensors to detect a ...

Allegro MicroSystems today announced three ICs: two analogue current sensors and a motor driver for fans. The first current sensor, ACS37630, is designed to be sat on top of a bus bar and partly surrounded by a U-core magnetic field concentrator. “Its vertical Hall technology enables sensing parallel to the package surface, ideal for system integration with U-core magnets,” according ...
