Melexis, a global microelectronics engineering company, announced today that it has launched the MLX90513 inductive sensor chip with excellent accuracy, designed specifically for automotive pedal and steering applications. Thanks to the MLX90513, this excellent performance is no longer limited to a few applications. This sensor interface chip reaches ASIL C level and has on chip digital signal processing function, which can enhance zero delay performance.
For many applications that require position sensing, the combination of high-precision and complete resistance to stray magnetic fields can achieve unparalleled performance, fully meeting the needs of existing applications.
performance
The new position sensor chip MLX90513 launched by Melexis can provide ± 0.1% full scale accuracy (± 0.36 ° in a rotating implementation within the 360 ° range). In addition, it is below 20 μ The delay of s can be reduced to zero through programming, which means fast control of the loop can be achieved, ensuring excellent system responsiveness. This inductance based standard product has natural immunity to stray electromagnetic fields (ISO 11452-8 standard requirements). Meanwhile, the sensitivity of the sensor chip is not affected by thermal drift.
Flexible output
The output of this sensor chip can be configured with options that allow position sensing data to be transmitted as proportional analog signals, PWM, SENT, or SPC signals. Therefore, it can adapt to many output protocols related to different application standards. MLX90513 is a market leading inductive position sensor chip with SPC output. Another major advantage of this product is its 0.5 µ s tick time (fast SENT or SPC) function, which has not yet been available in the market as an inductive position sensor chip. In addition, the ability to achieve pulse shaping in PWM, SENT, and SPC modes is also crucial as it helps to reduce electromagnetic radiation.
application
MLX90513 can be used for:
• Accelerator/accelerator/brake pedal displacement detection
• Steering wheel corner position detection
• Valve or actuator angle position detection
• Long stroke linear applications (up to 30cm)
Considering the importance of functional safety (ISO 26262), this sensor chip supports system integration up to ASIL D level. In addition, MLX90513 can be used in conjunction with Melexis‘ magnetic sensor chips to achieve system redundancy, as these devices do not interfere with each other (i.e. do not generate crosstalk).
robustness
The MLX90513 features a compact TSSOP-16 package with a working temperature range of -40 ℃ to+160 ℃, making it suitable for installation in challenging application environments. Due to the use of harmonic filtering, the three-phase coil layout used can improve linearity. The 32 point linearization of this device helps to correct angle nonlinear errors. Overvoltage and reverse polarity protection can further ensure the robustness of its operation. Due to the use of inductance measurement methods, system implementation has been greatly simplified and integration has become easier.
First tier suppliers hope to use high-precision position sensing technology, "said Lorenzo Lugani, Product Manager of Melexis Inductive Sensor Chip." Thanks to our MLX90513 device, the inductive position sensing solution can benefit more users
