The new MLX90376 from Melexis<\/a><\/strong> is an absolute magnetic position sensor IC, handling 360\u00b0 rotary automotive applications with strong stray field immunity (SFI). Its dual-stacked die PCB-less version is unique to the market. The device supports system integration up to ASIL D level functional safety, offering state-of-the-art sensing for steering and valve applications. The blend of robustness and performance it offers will be of value for vehicle electrification.<\/p>\n\n\n\n

Based on proprietary technology, the MLX90376 belongs to the Triaxis high-end family. Especially designed for demanding steering wheel angle, throttle valve and thermal management valve applications, this IC has a unique combination of features. These include:<\/p>\n\n\n\n

Option<\/strong> for dual stacked die in a PCB-less solution<\/p>\n\n\n\n

ASIL <\/strong>C Safety Element out of Context (SEooC), supporting up to ASIL D system integration (ISO 26262)<\/p>\n\n\n\n

SFI<\/strong> of up to 5mT (4000A\/m) for 360\u00b0 rotary applications (ISO 11452-8)<\/p>\n\n\n\n

This position sensor can be housed in either SMP-4 PCB-less or surface-mount device (SMD) packaging. Use of the SMP-4 version makes mechanical integration easier, speeding up development and design. The dual stacked die is a major benefit versus off-axis tolerances, which is critical for applications such as electric power steering (EPS). The SMD versions are supplied in SOIC-8 (for single-die) and TSSOP-16 (for dual-die) package formats. The MLX90376 is ASIL compliant and has been developed as an ASIL C S SEooC as per ISO 26262. Specifying a dual-die MLX90376 provides redundancy for safety-critical applications, allowing the device to support system integration up to ASIL D. The MLX90376 IC exhibits SFI up to 5mT (4000A\/m) for 360\u00b0 rotary applications (ISO 11452-8). This mitigates the sources of electromagnetic noise regularly found within electric cars. <\/p>\n\n\n\n

The MLX90376 offers output options to suit various applications: Analogue, PWM, SENT, or the specific SENT Short PWM Code (SPC). The SPC protocol is SENT compatible with bi-directional commands via a bus interface. This modern protocol simplifies in-vehicle networking infrastructure (limiting wires to save cost and weight) and facilitates system architecture for safety concepts up to ASIL D. It typically benefits applications involving multiple critical valves.\u00a0<\/p>\n\n\n\n

Support for high operating temperatures up to 160\u00b0C enables position sensing in extremely hot environments such as within engine compartments.<\/p>\n\n\n\n

To ensure first-time-right electromagnetic compatibility testing, the MLX90376 requires only one test cycle. This shortens design times and lowers costs. It is similar to the performance of the established MLX9037x high-end family.\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"
