The MLX90364 Triaxis® is a high accuracy linear and angular position sensor, from Melexis, which eliminates the need for inclusion of a printed circuit board (PCB) within sensing modules. This device is based on a dual mold package construction, which integrates a 12-bit resolution position sensing die together with the decoupling capacitors necessary to meet the strenuous electro-static discharge (ESD) and electromagnetic compliance (EMC) requirements of automotive environments. Once encapsulated, this dual mold package can be welded or soldered directly to a rugged connector or termination and further potted or over-molded. The dual mold package simply makes the need for a conventional PCB arrangement redundant. Dedicated ears allow greater accuracy levels to be realized when mounting.
The sensor device can be used in either linear or rotary position sensing applications. It features fully programmable transfer functionality, selectable analog and pulse width modulation (PWM) output modes, open/short diagnostics, on-board diagnostics, under-voltage detection and over-voltage protection. A SENT-SAE J2716 capable version is currently under development.
The MLX90364 combines the dual mold package with our latest generation of Triaxis® position sensor ICs. By using fewer components and lowering the number of solder-joints by more than a factor of 3, the risk of failures is decreased greatly. PCB-less mounting allied to contact-less sensing offers a solution that is fully optimized for long term reliable performance.
The MLX90364 is qualified according to the AEC-Q100 and Q200 automotive standards. It has passed extreme robustness validation tests, such as long exposures to ambient temperatures up to 170°C.
