Latest position sensor supplied in new PCB-less packages

04-06-2021 | Melexis | Automotive Technologies

Melexis has launched the MLX90377 single and dual-die (fully redundant) Triaxis position sensor for automotive and industrial applications with a new PCB-less package for position sensors.


The device is a magnetic rotary and linear position sensor IC, which develops on the success of the MLX90371 and MLX90372 Triaxis sensors. Based on the Triaxis Hall magnetic front-end, it combines an ADC with signal conditioning, DSP and an output stage driver that now supports SPC (Short PWM Code) and also ratiometric analog, PWM, and SENT signal formats. As other members of the Triaxis position sensor range, it can be employed in rotary and linear motion position sensing applications. With its stray field robust modes, ASIL-C (single die) capability, and external pin measurement, it is ideal for high performance and safety-critical applications.


The new package options include the SMP-3 and SMP-4 (single mould package, 3 and 4-pin) for PCB-less designs. Like its first PCB-less package, the DMP-4, released in 2012, these new packages are designed to be utilised without a PCB, thereby lowering total system cost and increasing mechanical integration and reliability. These new package outlines are smaller than the current DMP-4 package and provide better mechanical integration and quality through optimisation of the package body and electrical leads, representing almost a decade of continuous improvement based on customer feedback and application knowledge. The SMP-3 is a single die solution and will first be supported by the MLX90377 while the SMP-4 offers a dual die solution (shared power and ground pins) and will first be supported by the previously launched MLX90371.






“Melexis is constantly improving and expanding its product offering, by using its domain expertise to develop new solutions,” said Nick Czarnecki, marketing manager, Melexis. “The MLX90377 provides improved performance and adds SPC capability, which is now being used in multi-bus architectures such as those found in advanced steering and braking applications. The new package options are perfect examples of how Melexis listens to customers and works with its partners to improve quality and reduce costs.”
