XP Power has released two baseplate-cooled dc-dc converter series with 14 to 160Vdc (12:1) inputs. Nominally running from 72V rails, they are rated at 150W (RDF150 series) or 200W (RDF200 series) and designed for use in railway, renewable energy and industrial applications. “The voltages available in railway applications vary globally, often requiring different power designs to suit each geography,” according ...

The MIPI Alliance has released version 2.0 of its A-PHY asymmetric SerDes (serialiser-deserialiser physical-layer interface, doubling its down-link speed to 32Gbit/s, and increasing its top up-link speed eight-fold to 1.6Gbit/s. “These enhancements are designed to support the higher bandwidth requirements for zonal and other emerging architectures in next-generation vehicles,” according to the MIPI Alliance. “To aid implementation, no changes were ...

SiTime has announced a series of clock generators for automotive systems, calling them: “Industry’s first integrated clock system-on-a-chip with built-in fault monitoring mechanisms for the entire clock generation signal path, with the capability to alert a safety microcontroller of a clock-related fault within microseconds instead of milliseconds.” The devices, branded Chorus, include a MEMS resonator, oscillator and safety mechanisms into ...

Renesas has expanded its R-Car family of driver assistance processors with lesser-performance additions to its V4 range – headlined by the two-year old V4H-7. With 34Top/s of AI processing, V4H-7 is aimed at Level 2+ and Level 3 automated driving, over-kill for Level 1 and Level 2 automation. The additions are: 27Top/s V4H-5 24Top/s V4H-3 17Top/s V4M-7 14Top/s V4M-5 11Top/s V4M-3 ...

From rotating magnets, Melexis is intending to generate two quadrature outputs with “minimal jitter as well as consistent 90° phase shift regardless of magnet pole pitch” from single IC containing two magnetic Hall sensors. The aim is to replace pairs of accurately-spaced single Hall sensor ICs with a single new IC, called MLX92253, that uses precision angles to replace precision ...

NXP is aiming at ASIL D safety approval with a vehicle battery junction box controller IC, intended to fire the pyrotechnic disconnect switch during a serious fault, as well as report faults over a serial bus. MC33777A, as it will be known, redundantly measures currents, voltages and temperatures, then deduces situations – a short circuit or a crash, for example ...

Nexperia has put more single and dual small-signal mosfets into DFN1110D-3 (SOT8015) and DFN1412-6 (SOT1268) packages, with side-wettable flanks for automated optical inspection. “The 1.1 x 1mm DFN1110D-3 package has seen increasingly wide adoption, and is quickly becoming the de-facto industry standard package for small-signal mosfets and bipolar transistors intended for use in automotive applications,” according to the company. “Superior ...

TDK has introduced a series of high-value metal-framed multi-chip ceramic capacitors for automotive electric power trains, on-board chargers and wireless power transfer systems, where the capacitors must handle high currents or voltages, or have high capacity. “To meet these needs, TDK developed the CA series, the largest MLCCs in the industry [6 x 5.6 x 6.4mm] with a metal frame ...

Magnachip has come up with four new 40V MXT MV MOSFETs designed in PDFN 33 packages for automotive applications. PDFN33 packages reduce footprint by more than 60% and the weight by approximately 75% compared to PDFN56. Three of the devices – AMDV040N029LVRH, AMDV040N036LVRH, and AMDV040N042LVRH – have a gate threshold voltage of 1.8V. Magnachip’s New Automotive 40V MXT MV MOSFETs The key ...

Vishay has added five solenoid-based haptic actuators to its IHPT range, which come with operation licenses from Immersion Corporation. There are four sizes, from 29 x 21mm to 44 x 37mm, that can provide forces up to 120N. Not immediately obvious from the photo, each transducer us in two parts: the top left part is a separate laminated metal bar ...
