Theisen DelO, Belgium, April 11, 2024 - Melexis, a global microelectronics engineering company, today officially launched the innovative Induxis? Switch chip MLX92442. This single-chip solution enables direct detection of conductive targets thanks to its contactless design, magnetise-free nature, and excellent resistance to stray field interference. The product not only supports small module design, significantly reduces the number of components, and performs well in increasing safety and electrification levels. A wide range of applications include high-voltage interlocks, charging port covers, seat belts, hood/trunk, gear sensing or drive-by-wire braking.
Traditional automotive safety latches and switches, such as door and trunk handles, seat belts, and brake light switches, often use mechanical contact or magnetic switches, such as key switches, reed tubes, or Hall effect sensors. However, these solutions often require modifications to the design of the safety target when applied, such as the addition of magnets, brackets, or physically raised trigger buttons.
Melai‘s innovative inductive solutions revolutionize this traditional model. Its unique technology can directly sense actual safety targets, such as seat belt buckles or door locks, without the assistance of magnets or push-button actuators. As long as the target conducts electricity, accurate and reliable detection can be achieved.
Milaxin‘s innovation in position sensing technology brings a number of significant advantages. The technology eliminates traditional moving mechanisms and additional components, making direct sensing operation more reliable and safe, and no longer relying on safety components that can be damaged or displaced. In addition, this innovative solution helps simplify the logistics list (BOM). Inductive contactless operation is not only more reliable than traditional mechanical solutions, resistant to wear over time, but also resistant to magnetic interference, ensuring stable system operation.
Cutting-edge design
The core advantage of the MLX92442 is its highly integrated and miniaturized standard package design. What makes this solution unique compared to other inductive solutions is the complete integration of coils and interfaces inside the chip, eliminating the need for developers to develop bulky PCB and coil solutions for applications.
To meet the needs of different applications, the solution offers a flexible choice of pin VK package or surface mount SOIC package. Regardless of the package, the BOM is reduced from 3 components to 2 components (target + chip/coil) compared to existing solutions. Combined with the magnet removal properties described above, this innovation helps produce designs that are more sustainable and safer than existing sensors on the market.
To ensure continuous and reliable operation, the MLX92442 also integrates reverse supply voltage, undervoltage and thermal protection mechanisms, as well as advanced integrated self-diagnostics with a dedicated safety mode.
Simplified integration
Millicore‘s inductive solutions do a great job of simplifying integration, not only reducing the number of BOM components, but also significantly saving development time. It supports programming at the end of the factory and production line, making smart switch/latch operation a breeze, simply by defining the shape and motion of the application. The solution eliminates the need for magnetic simulation compared to traditional Hall effect solutions, resulting in shorter development cycles (an advantage second only to significant BOM savings).
In terms of assembly design, the MLX92442‘s standard package and the absence of magnets and brackets make system integration easier. This design not only simplifies the supply chain, but also reduces the number of components, helping to reduce prototyping and production assembly time. In addition, this solution helps to maintain mechanical tolerances in the assembly, as only the matching of inductive sensors and conductive safety elements within an air gap of up to 1.5mm is considered.
The MLX92442 features industry standard two - or three-wire interfaces, A wide operating voltage of 3.5V to 18V and an operating temperature range of 40 ° C to 150 ° C, as well as ISO26262 ASIL A compliance, making design considerations extremely simplified. For safety-critical applications that require redundancy, the MLX92442‘s inductive technology offers a highly reliable option with low design requirements that can operate alongside Hall effects and mechanical solutions.
Ready for evaluation
"By adopting this new technology, our engineering team has succeeded in redefining terminal location sensing, bringing numerous advantages to users," said Minko Daskalov, Product Manager at Melai Core. It aims to drive continued advances in electrification and safety technologies to support key areas such as batteries for power grids and electric vehicles, as well as hydrogen technology. The MLX92442 fits every need perfectly."
The MLX92442 is currently in pre-production and we offer engineering B samples and evaluation kits.
