Melexis expands IMC-Hall® current sensor portfolio exceeding measurement

Posted on by mixos

Melexis, a global microelectronics engineering company, has introduced the MLX91216 XHF extra high-field current sensor, extending the ease and accuracy of its unique IMC-Hall® technology into high-current measurement for emerging automotive applications.

Capable of measuring current to beyond 2000 A, the MLX91216 XHF is suited to redundant monitoring of battery-management systems (BMS), over-current detection in smart fuses, and measuring phase currents in traction inverters and boost/recuperation inverters. With user-programmable filtering to adjust resolution, response time, and bandwidth for optimum signal-to-noise ratio, the sensor features built-in diagnostics, including broken-wire detection.

The SOIC8 surface-mount device contains Melexis’ patented Integrated Magnetic Concentrator (IMC) that enables accurate contact-free measurement of busbar current in combination with a simple U-shape magnetic shield. When mounted on a PCB, the sensor is positioned over the busbar, within the shield, allowing easier assembly than conventional Hall sensors. What differentiates the proven IMC-Hall® technology from coreless solutions is that position is much less critical. The design can accept more mechanical movement because the measurement is not dependent on a magnetic field gradient. Other technologies that are can result in very severe bus bar machining causing important thermal hot spots. On the other hand, IMC-Hall® technology carries the advantages of coreless technologies, so it lends itself to smaller assemblies with surface mount package solutions. This avoids the use of more complex through-hole packages that often require specific lead bending/forming native to core-based solutions.

The MLX91216 XHF extends the family of Melexis IMC-Hall® sensors that provide accurate, high-speed current measurement for a wide range of automotive and industrial applications.

  • MLX91216 High field (HF) versions: 200 to 600 A
  • MLX91216 Very High Field (VHF) versions: 400 to 1200 A
  • MLX91216 eXtra High Field (XHF) versions: 800 to 2000 A

Available now, the MLX91216 XHF is AEC-Q100 Grade-0 qualified for automotive applications and operates over the temperature range -40 °C to +150 °C. The sensor has a wide measurement range from ±20 mT to ±350 mT with linearity down to ±0.2% full scale, 2 μs response time, and high thermal stability with offset drift below 5 mV and sensitivity drift within 1%.

AAEON Partners with KingTiger and AMI to Accelerate Deployment of iMS Memory Error Prevention Software

Posted on by mixos

AAEON, an industry leader in edge computing solutions, collaborated with KingTiger, a leader in memory testing solutions, to help with testing and developing their intelligent Memory Surveillance (iMS) memory error prevention software. Developed in conjunction with AMI, a leading provider of firmware, manageability and security solutions for the global computing industry, this innovative software, which is embedded in Aptio V UEFI Firmware from AMI, allows systems to avoid memory errors without ECC support, ensuring secure, reliable, and accurate data reporting in edge computing and big data systems.

Data integrity is vital for a wide range of big data and data-based applications. From medical records to finance, memory errors can wreak havoc on accuracy, reliability and even data safety and security. For larger and more powerful computing systems, this is usually solved with the use of error-correcting code (ECC) memory. However, ECC memory is often limited based on whether or not the processor chipsets support this hardware solution. This often requires developers and users to upgrade their hardware platforms to higher performance, and thus more expensive, platforms where the extra power and cost are otherwise unjustified, such as in edge computing applications.

KingTiger, specialists in memory testing solutions, recently developed iMS, a software-based approach to error correction memory. The iMS, or intelligent Memory Surveillance, software is deployable on platforms which otherwise don’t support ECC memory, allowing developers and users to use platforms with more appropriate processing capabilities, saving costs while maintaining data integrity. The software can detect erroneous bits and mask them before they cause errors within the data and avoid system crashes. iMS provides an advantage over ECC memory in that it can detect and mask an unlimited number of bits, whereas ECC memory is typically limited to one bit per address. It also, in effect, extends the lifecycle of memory/RAM modules by being able to handle a greater number of error bits.

KingTiger worked with AMI to integrate the iMS software into Aptio V UEFI BIOS Firmware from AMI. As longtime users of AMI’s UEFI BIOS Firmware and with expertise in OEM/ODM platform testing, AAEON provided support through testing the iMS integrated Aptio V UEFI Firmware on a range of platforms featuring the 8th Generation Intel® Core™ U processors (formerly Whiskey Lake). Thanks to these efforts, KingTiger is officially launching iMS, and AAEON will soon be offering the Aptio V UEFI Firmware with embedded iMS on their 8th Generation Intel Core based products in early 2021, and plans to have the KingTiger iMS featured on the soon to be released lineup of platforms with 11th Generation Intel® Core™ U processors (formerly Tiger Lake).

Latest Higher Resolution EVE ICs from Bridgetek Now Designed into High-End Riverdi Displays

Posted on by mixos

Bridgetek has gained a high-profile endorsement for its latest generation of embedded video engine (EVE) graphic controllers. Relying on the recently announced BT817 EVE4 devices, leading optoelectronics manufacturer Riverdi has introduced a new family of displays. These industrial-grade units are targeted at challenging higher-end applications but are positioned at attractive price points that are in line with commercial level products.

Thanks to the heightened degrees of precision associated with the BT817 ICs, the new Riverdi displays are able to benefit from 1280×800 pixel resolution. Treating the rendered content as a series of objects reduces the data overheads involved dramatically. This translates into a more streamlined solution, with a substantially lower component count plus accelerated responsiveness.

“By engaging with Bridgetek, we have been able to develop a display family that sets new benchmarks. The ultra-integrated EVE4 solution means that quicker reaction times and superior resolution levels are possible, while still saving valuable board space and keeping power budgets down,” states Kamil Kozłowski, CTO at Riverdi. “Consequently, we have decided to take a platform approach and apply it across the whole family, from the smaller units all the way up to the largest formats,”

“It is clear that the user experiences which people are familiar with from interacting with consumer goods have set elevated expectations for HMIs in other areas too,” adds Bridgetek’s founder and CEO Fred Dart. “Higher resolution displays with faster responsiveness are now mandated in a wide array of different sectors. This is why the value of our BT817 and BT818 is becoming so apparent to OEMs, giving them the opportunity to meet their customers’ requirements without needing complex expensive subsystems that take up board real estate or draw excessive power.”

The EVE-based Riverdi displays are available in a wide range of different size formats, spanning from 3.5-inch all the way through 4.3-inch, 5.0-inch, and 7.0-inch to 10.1-inch. Use of in-plane switching (IPS) technology results in a brighter output (delivering up to 1000cd/m2). It also means that these units have enhanced color rendering and much wider viewing angle capabilities. Optical bonding is incorporated into the display assemblies as standard, even for single pieces – thereby preventing condensation, mitigating internal reflections, and boosting optical performance, as well as delivering far greater durability. The projected capacitive touchscreens featured in these displays allow touch interaction through the protective glass that is as much as 15mm thick and also enables gloved operation to be supported.

Assisted by innovative Bridgetek engineering, the new Riverdi displays are optimized for addressing the most demanding tasks. They will be implemented into medical diagnostic instrumentation, home healthcare monitoring equipment, electric vehicle charging infrastructure, industrial automation systems, vending machines, etc. Exceptionally strong electro-magnetic interference (EMI) and electro-static discharge (ESD) immunity characteristics are exhibited, along with a working temperature range covering -20°C to +70°C.
