Melexis Launches Integrated Inductive Switch Designed for EV Transmission Systems
Melexis Revolutionizes Automotive Safety with Contactless Inductive Switch
Melexis, a leading innovator in microelectronics for automotive applications, has unveiled the MLX92442, a groundbreaking inductive switch named Induxis. This revolutionary technology promises to significantly enhance safety and efficiency in electric vehicles (EVs) and beyond.
Eliminating Mechanical Complexity: A Leap Forward in Safety Systems
Traditional automotive safety latches and switches, such as those used for doors, trunks, seatbelts, and brake lights, often rely on mechanical contacts or magnetic switches. These solutions require modifications to safety targets, including the addition of magnets or physical protrusions. The Induxis switch disrupts this paradigm.
Induxis: The Power of Simplicity and Reliability
Melexis' Induxis switch takes a fundamentally different approach. This innovative solution utilizes inductive technology to directly detect conductive targets, eliminating the need for magnets or buttons altogether. This shift offers several compelling advantages:
- Enhanced Reliability and Safety: By removing moving parts and additional components, Induxis offers direct sensing, reducing the risk of failure due to damaged or displaced mechanical parts.
- Reduced Bill of Materials (BOM): Induxis simplifies the design by requiring only two elements – the target and the integrated circuit (IC) with built-in coils. This translates to cost savings and a more streamlined manufacturing process.
- Superior Durability: Unlike mechanical solutions prone to wear and tear, Induxis' contactless operation ensures long-term reliability.
- Immunity to Magnetic Interference: Induxis is unaffected by stray magnetic fields, a common challenge for traditional magnetic switch technologies.
State-of-the-Art Design for Seamless Integration
The MLX92442 boasts a highly integrated and miniaturized design. Unlike other inductive solutions requiring bulky external coils and complex PCB layouts, Induxis integrates everything within the chip itself. This simplifies the design process for engineers and offers two convenient packaging options:
- Through-hole VK packaging
- Surface-mount SOIC packaging
Furthermore, the Induxis switch incorporates several features to ensure exceptional reliability:
- Reverse supply voltage protection
- Under-voltage protection
- Thermal protection
- Advanced integrated self-diagnostics with a dedicated safe mode
Streamlined Development and Simplified Assembly
Beyond BOM reduction, Induxis offers significant benefits for development and assembly:
- Simplified Programming: The switch/latch operation can be easily configured by defining the target's shape and motion, eliminating the need for complex magnetic simulations required by Hall effect solutions. This translates to faster development times.
- Standard Packaging: The standard packaging and elimination of magnets simplify system integration and streamline the supply chain. This reduces prototyping and production assembly time, while also minimizing the impact on mechanical tolerances.
- Wide Compatibility: The MLX92442 boasts industry-standard two or three-wire interfaces, a wide operating voltage range (3.5 V to 18 V), a functional temperature window of -40°C to 150°C, and ISO26262 ASIL A compliance. This ensures compatibility with diverse applications.
- Heterogeneous Redundancy: Induxis presents a highly reliable solution for safety-critical applications requiring redundancy. It can operate seamlessly alongside Hall effect and mechanical solutions.
