Cutting-Edge: Fully Integrated Inductive Switch Technology

Melexis, a leading semiconductor company, is making waves in the automotive industry with the introduction of its latest innovation - the Induxis switch, known as the MLX92442. This cutting-edge switch is contactless, magnet-free, and strayfield immune, making it a monolithic device that directly detects conductive targets. The company is currently in the sampling phase of this groundbreaking technology, which is set to revolutionize the way safety and electrification features are integrated into vehicles.

One of the key advantages of the MLX92442 is its ability to enable small module designs with a reduced component count. This not only improves safety standards but also enhances electrification features such as high voltage interlocks, charging flaps, seatbelts, hood/trunk sensors, gear tooth sensing, and brake-by-wire applications. By eliminating the need for traditional mechanical contacts or magnetic switches, Melexis is paving the way for a more efficient and reliable automotive design.

Traditionally, safety automotive latches and switches rely on mechanical contacts or magnetic switches like push buttons, reed switches, or hall effect sensors. However, these solutions often require modifications to the safety target's design, such as adding a magnet or physical protrusion. With Melexis' induction technology, this is no longer necessary. The MLX92442 can actively sense safety targets like seat belt buckles or door latches directly, without the need for additional components.

The shift towards inductive technology offers several benefits, including enhanced reliability and safety. With no moving parts or external components, the MLX92442 provides a more robust solution that is not susceptible to wear and tear over time. Additionally, the contactless operation is immune to magnetic interference, further improving the overall performance of the switch.

Central to the MLX92442's design is its highly integrated and miniaturized packaging, which sets it apart from other inductive solutions on the market. Melexis has innovated by fully integrating the coils and interface within the chip, eliminating the need for bulky PCB and coil solutions. This streamlined design reduces the bill of materials and simplifies the integration process for engineers, ultimately leading to a more sustainable and safer end product.
