Support for Peripheral Sensor Interface 5 will further reduce implementation costs.
Tessenderlo, Belgium, 25 June 2019 - Melexis announces the MLX90373, part of the Triaxis® rotary and linear Hall-effect position sensor family and the first Triaxis® angle sensor to offer support for the PSI-5 interface.
The PSI-5 (Peripheral Sensor Interface 5 - www.psi5.org) is an open standard based on the technology used in millions of air bag safety systems. This highly responsive technology delivers a data bit rate of 125 kbit/s over a 2-wire unshielded cable, making it suitable for a wide number of automotive sensing applications now applied to safety and comfort, such as steering and chassis ride height measurement. The 2-wire implementation makes it simpler and fundamentally less costly to deploy than other forms of serial interface that require 3- or 4-wire cabling.
The MLX90373 Triaxis® Hall-effect sensor offers both rotary and linear position sensing in a robust design that simplifies the magnetics' design for the manufacturer. The extended ambient temperature of -40 °C to +125 °C, on-chip diagnostic features and a gateway input for external sensors are combined in a design that offers all the benefits of the PSI-5 interface, including flexibility when using the four time-slots available, along with provision for additional external sensor data to be added to the payload.
Nick Czarnecki, Global Marketing Manager Position and Speed Sensors at Melexis, said: 'The MLX90373 is a great step forward for the third generation Triaxis® family, as it delivers all of the benefits of our industry-leading 3D sensing technology to a new implementation paradigm, one that can help lower the cost of adoption for more automotive manufacturers and the advantages that offers their end customers.'
As with all Triaxis® sensors, the MLX90373 has been developed to support PCB-less mounting and offers excellent EMC performance. It also meets the requirements for ISO 26262 ASIL C (SEOoC) and is offered in a dual-die, fully redundant version in a TSSOP-16 package. The option of choosing the PSI-5 interface means the Triaxis® rotary and linear Hall-effect sensor family now covers PSI-5, PWM, Analog and SENT interfaces.
Now in its third generation, Melexis' Triaxis® technology continues to evolve, by combining the latest industry-standard interfaces with a high level of integration, along with the flexibility and robustness that automotive manufacturers require in order to provide the latest safety and comfort features to consumers.
