On September 27, 2024, Tyson Delo, Belgium - Melexis, a global microelectronics engineering company, announced the launch of a dual chip stacked version of MLX90425 and MLX90426, expanding its innovative Triaxis magnetic sensor chip series. The new version of the chip launched this time has a 5mT stray magnetic field immunity (SFI) and supports 360 ° magnet rotation detection, which can meet the safety requirements of steering wheel and accelerator pedal position sensing and help improve the level of autonomous driving.

With the increasing demand for vehicle autonomy, the level of automotive electrification is gradually improving, and the widespread application of "line control" technology is gradually replacing traditional mechanical connection systems. In this field, especially for the wire control design of core systems such as steering, throttle, and braking, it highly relies on reliable sensing technology with built-in redundancy mechanisms. This redundancy mechanism is crucial for ensuring the functional safety and availability of critical systems. In addition, facing the booming electric vehicle (EV) market, the ability to resist stray magnetic field interference is also an indispensable technical requirement, ensuring that sensors can still accurately measure in complex electromagnetic environments.

In response to the automotive industry's demand for improved autonomy, safety, and electrification, Mindray has expanded its highly acclaimed anti stray magnetic field 360 ° rotation detection chip series and launched a dual chip stacked version of MLX90425 and MLX90426. This design integrates the two chips into a single TSSOP-16 (SMD) or SMP-4 (no PCB required) package. This innovative design not only complies with the ASIL C standard, but also supports the highest ISO 26262 ASIL D-level system level integration, meeting the increasingly stringent safety standards of the automotive industry. Compared to traditional discrete dual chip solutions, the dual chip stacked versions of MLX90425 and MLX90426 achieve significant improvements in integration. Both chips have excellent accuracy and can maintain precise measurements in stray magnetic field environments up to 5mT, ensuring the accuracy and reliability of data. In addition, they also have customized specification options aimed at providing strong support for customers to create cost-effective terminal solutions.

The core of MLX90425 and MLX90426 is based on the magnetic induction technology of Mindray, which can accurately measure magnetic flux in a single chip. They not only have programmable linear transmission characteristics up to 17 points, but also support a wide operating temperature range from -40 ℃ to 160 ℃, making them very suitable for automotive applications.

The launch of the MLX90425 and MLX90426 dual chip stacked versions not only further expands the Triaxis? Series, but also provides customers with a one-stop comprehensive solution to meet their latest functional and cost control requirements. The newly launched dual chip version will provide strong support for the popularization of vehicle line control technology, the development of autonomous driving technology, and the comprehensive upgrade of ADAS (Advanced Driver Assistance System) functions, "said Lorenzo Lugani, Product Line Director of Mailaixin

The new MLX90425 and MLX90426 dual chip stacked versions are now available in TSSOP-16 (SMD) or SMP-4 (without PCB) packaging.
