Melexis has expanded its portfolio of 3D magnetic position sensing solutions with the introduction of the MLX9042x series.

These sensors are intended for cost-conscious automotive customers who need to measure absolute position accurately and safely in harsh and noisy environments over an extended temperature range.

The solutions are primarily intended for automotive customers working on applications such as powertrain actuators, transmission sensors, pedal position sensors and chassis sensors. Industrial customers will also benefit from the improvements they enable.

Based on Triaxis Hall sensor technology, the MLX9042x devices all feature analogue signal conditioning, data conversion and signal processing, as well as output stage drivers.

The devices in this series are:

To ensure first-time-right EMC testing the MLX9042x offer similar performance as the products in the MLX9037x family. Only one test cycle is required, keeping the design progressing quickly and the costs low. The high absolute maximum ratings (AMR), including reverse polarity, reduce the number of quality incidents due to electrical overstress and allow the achievement of various OEM requirements.

ASIL B ready (per ISO 26262), these devices enable the design of functionally safe actuators and sensors to ensure safe operation of the vehicle. As well as single die versions, dual die versions are available for applications requiring higher levels of safety and availability.

Another key benefit includes support for 160 °C operational temperatures. The high temperature capability enables position sensing applications in hot environments - such as small engine compartments or where start-stop conditions cause increased heat soaks.

The Melexis MLX9042x devices are all fully AEC-Q100 qualified and can be supplied in SMD packages or in SMP-3 and SMP-4 PCB-less packages (where the sensor and EMC capacitors are integrated into a single mold).

The MLX90423, MLX90425 and MLX90426 sensors are capable of rejecting stray magnetic fields (up to 5 mT or 4000 A/m) in rotary and linear position sensing applications.
