On September 27th, global microelectronics engineering company Melexis announced the latest stackable version of MLX90425 and MLX90426, expanding its innovative Triaxis ®magnetic sensor chip family.
The new version of the chip has 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 to improve the level of autopilot.
With the increasing demand for vehicle autonomy and the gradual improvement of the level of automobile electrification, the wide application of “line control” technology is gradually replacing the traditional mechanical connection system.
In this field, especially the wire control design for core systems such as steering, throttle and brake, highly depends on the reliable sensing technology with built-in redundancy mechanism.
This redundancy mechanism is very important to ensure the functional security and availability of critical systems.
In addition, in the face of the booming electric vehicle (EV) market, the ability to resist stray magnetic field interference is also an indispensable technical requirement, which ensures that the sensor can still measure accurately in a complex electromagnetic environment.
MLX90425BAA-SMP4 package product map, in response to the needs of the automotive industry to improve autonomy, safety and electrification, McLaren extends the highly acclaimed family of anti-stray magnetic field 360 °rotation detection chips to introduce a two-chip stackable version of MLX90425 and MLX90426, which integrates the two chips in a single TSSOP-16 (SMD) or SMP-4 (no PCB) package.
This innovative design not only complies with ASIL C standards, but also supports up to ISO 26262 ASIL D-level system-level integration, meeting the increasingly stringent safety standards of the automotive industry.
Compared with the traditional discrete dual-chip solution, the dual-chip stackable version of MLX90425 and MLX90426 achieves a significant improvement in integration.
Both chips have excellent accuracy and can maintain accurate measurements in stray magnetic field environments up to 5mT, ensuring the accuracy and reliability of the data.
In addition, they have customized specification options designed to provide strong support for customers to create cost-effective terminal solutions.

They not only feature programmable linear transmission up to 17:00, but also support a wide operating temperature range from-40 ℃ to 160 ℃, making them ideal for automotive applications.
The difference between the two chips lies in the output protocol: MLX90425 provides proportional analog output or PWM output, while MLX90426 provides digital SENT output.
Lorenzo Lugani, director of McLaren’s product line, said, “the introduction of the dual-chip stackable version of MLX90425 and MLX90426 not only further expands the Triaxis ®series, but also provides customers with a comprehensive one-stop solution to meet their latest functional and cost control requirements.
The new dual-chip version will provide strong support for the popularization of vehicle wire control technology, the development of self-driving technology and the overall upgrade of ADAS (Advanced driving Assistance system) functions.
” The new dual-chip stackable versions of MLX90425 and MLX90426 are now available in TSSOP-16 (SMD) or SMP-4 (no PCB) packages.
