ROHM has developed an ultra-compact high output linear LED driver IC (BD18336NUF-M) that gives stable lighting even in the case of battery voltage drops on a single chip, making it excellent for a wide range of socket-type LED lamps employed in vehicle systems, from DRLs and position lighting to rear lamps.

The device adopts a current bypass function that stops LED turn OFF and sustains a brightness of at least 30% at all times by switching the LED current path, even when the battery voltage reduces from 13V to 9V. Also, a high output of 600mA is delivered in an ultra-compact 3mm square package, and mounting area is decreased by approximately 30% over conventional solutions (including the external circuit), making mounting feasible on the 10mm square substrates needed for small socket-type LED lamps.

Conventional products, when configured with no external circuitry, can cause the LED lamps to turn OFF when the battery voltage drops, likely creating an unsafe situation throughout vehicle operation. However, the company's new LED driver IC provides stable lighting while contributing to the greater miniaturisation of socket LED lamps. A function for suppressing LED heat generation is also built-in that supports white LEDs that typically run hot, enabling them to be employed in DRLs and other vehicle lighting systems using white LEDs.

U-blox has announced the ZED-F9T high accuracy timing module. This module satisfies even the most stringent timing synchronisation demands in 5G mobile networks on a global scale.

“The ZED-F9T’s nanosecond-level timing accuracy meets the most stringent requirements for 5G networks on a global scale. By significantly reducing the time error of the primary source of cellular network synchronisation, the ZED-F9T will help operators maximise the performance of their networks, and so optimise the return on their investment in 5G,” says Samuli Pietila, principal product management, Product Center Positioning at U-blox.

“The ZED-F9T also aims to address concerns regarding the integrity and resilience of GNSS-based timing synchronisation solutions for critical infrastructure applications,” Pietila adds. “The ZED-F9T will give network operators the capabilities to achieve unmatched immunity against spoofing and jamming attacks by combining concurrent reception of four GNSS satellite constellations with multi-band signal reception,” he adds, referring to the module’s ability to concurrently receive multi-band signals from America’s GPS, Europe’s Galileo, Russia’s GLONASS, and China’s Beidou satellites.

Also, the module’s support for all four GNSS constellations allows developers to create single products to serve global markets, simplifying OEMs’ product lines. The module has a single RF input for all the GNSS bands, simplifying antenna selection. An on-board diplexer, followed by dual SAW filters, gives excellent signal selectivity and out-of-band attenuation. Provided in a 54-pin land grid array package of just 17mm x 22mm x 2.4mm, it is intended for easy integration.

Murata has produced an all-in-one 24V standard battery module, that is excellent for any industrial equipment needing high levels of output such as AGV) and robots. The FORTELION 24V battery module is furnished with FORTELION, the company's proprietary Li-ion secondary battery, which employs an olivine type Li-ion phosphate as the cathode material which combes long life with a particularly high level of safety.

The company is committed to decreasing the usage of batteries that contain lead. This new module provides longer life, fast charging and a high level of safety as well as being the same size as an equivalent lead-acid battery.

As the new module delivers 24V, it can replace two series-connected 12V lead-acid batteries often found in many service robots, AGVs and electric forklifts. The module has an IP54 rating, providing protection against dust and water, and also satisfies the UL2271 safety demand for batteries for light electric vehicles, thereby verifying that it is safe for outdoor use.

The product satisfies the demand for long life in industrial applications. While lead-acid batteries typically need replacing at around 500 cycles and regular Li-ion batteries wear out after 2-3,000 cycles, the FORTELION technology is created to complete at least 10,000 charge-discharge cycles.

The company's extensive experience with PCs, mobile phones and other devices, as well as their unique arithmetic processing technology enables them to precisely calculate the residual battery capacity. This can be communicated to the wider system through the inbuilt CAN bus.

New Yorker Electronics has released the new Autec Power Systems’ HPN Series of AC/DC high power density power supplies. Nicknamed ‘The Marvel’, this speciality high power AutecFlex PSU has an input voltage of 187 to 277VAC (220VAC nom) and is single-phase (L-N) with three-phase optional.

Fully protected against output over-current, output over-voltage and continuous short circuit conditions, the series meets IEC/EN/UL 60601, IEC/EN 60335-1 and IEC/EN 60101-1-11 (2MOPP) standards.

The adapter meets CoC Tier 2 and DOE Level VI and is ideal for medical, healthcare and industrial applications.

Nexperia has launched a new AEC-Q101-qualified ASFET portfolio concentrated on powertrain applications. The technology has been tested to one billion avalanche cycles and may be employed to control automotive inductive loads including solenoids and actuators. Also providing a faster turn-off time (up to 4X), designs can be simplified through a smaller BOM count.

ACT96WJ43SC-6149

ACT96WJ43SC-6149MOSFET-based power schemes for solenoid and actuator control in automotive powertrains are commonly built around boost, free-wheel diode or active clamp topologies. A fourth option is a repetitive avalanche design that disperses energy from the inductive load by employing the MOSFET’s ability to constantly handle current from the inductive load through switch off. Providing comparable efficiencies to active clamp alternatives, such designs remove the requirement for diodes and other devices to minimise component count and circuit complexity. They also help faster switch-off times, a factor that can boost the reliability of electromechanical components such as solenoids and relays. When compared to boost topologies, they can simplify designs by delivering up to 30% component footprint efficiency due to a potential decrease of up to 15 board components.

Fully automotive qualified to AEC-Q101 at 175C, the new MOSFETs are offered in 40V and 60V options with typical RDS(ON) ratings from 12.5mOhm to 55mOhm. All of the devices are provided in the company’s space-saving LFPAK56D (Dual Power-SO8) copper-clip package technology. The robust package provides gull-wing leads for increased board level reliability and improved manufacturability, including AOI.

Explains Nexperia’s product manager, Richard Ogden “Typically, engineers looking to implement repetitive avalanche topologies have had to rely on devices that use older, planar semiconductor technologies. Offering automotive-qualified devices with guaranteed repetitive avalanche capabilities that are based on higher performance silicon structures will increase the number of powertrain designs that can take advantage of repetitive avalanche functionality.”

Anritsu has introduced the VectorStar ME7838G broadband VNA, claimed to be the industry’s first VNA able to make measurements from 70kHz to 220GHz in a single sweep. By giving unprecedented frequency coverage, the new VNA enables engineers to more accurately and efficiently characterise devices over a much wider range of frequencies to give accurate device models, therefore optimising the chance for accurate simulations and opportunity to decrease design turns.

Consistently producing the industry’s widest single sweep broadband coverage for improved device modelling is accomplished because the system includes the company's NLTL mmWave modules. Innovative design allows the 220 GHz probe to connect directly to the mmWave module for accurate, stable on-wafer measurements, thereby circumventing the limits of coaxial connectors at sub-terahertz frequencies.

The device meets the market demand to conduct on-wafer measurements that span into the upper mmWave frequencies for more accurate device characterisation. The VectorStar-based broadband system provides engineers confidence in the systems they are designed by characterizing the devices from near-DC to well beyond the operating frequency, for more accurate modelling.

X-FAB Silicon Foundries SE offers the availability of new high-voltage primitive devices aimed at the expanding market for automotive 48V board net and battery management system (BMS) ICs.
