Melexis Announces Latest Triaxis Position Sensor Together With New PCB-less Packages


MLX90377 supports more output signal formats while a new Single Mold Package (SMP) improves PCB-less integration and manufacturing costs

Melexis, a global microelectronics engineering company, has
introduced the MLX90377 single- and dual-die (fully redundant) Triaxis position
sensor for automotive and industrial applications together with a new PCB-less
package for position sensors.

The MLX90377 is a magnetic rotary and linear
position sensor IC, which builds on the success of the MLX90371 and MLX90372
Triaxis sensors. Based on the Triaxis Hall magnetic front-end, it integrates an
ADC with signal conditioning, DSP and an output stage driver that now supports
SPC (Short PWM Code) as well as ratiometric analog, PWM, and SENT signal
formats. Like other members of the Triaxis position sensor range, it can be
used 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 ideally suited for high performance and safety critical

The new package options comprise the SMP-3 and
SMP-4 (single mold package, 3- and 4-pin) for PCB-less designs. Like Melexis'
first PCB-less package, the DMP-4 released in 2012, these new packages are
intended to be used without a printed circuit board thereby reducing total
system cost and improving mechanical integration and reliability. These new
package outlines are smaller than the existing DMP-4 package and offer better
mechanical integration and quality via optimization of the package body and electrical
leads, representing nearly 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 provides 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.”
