MELEXIS MLX90513 inductive sensor IC enhances accuracy – especially for automotive pedal and steering applications. The ASIL C sensor interface features on-chip digital signal processing for enhanced zero-delay performances. The position sensor delivers a ±0.1% full-scale accuracy (±0.36˚ in a rotary implementation with 360˚ range). In addition, its sub-20µs latency, which can be reduced to zero through programming, means that a fast control loop can be implemented – resulting in improved system responsiveness being assured. This inductive-based ASSP exhibits native immunity to stray electromagnetic fields (ISO 11452-8 standard requirements). At the same time, this sensor is not affected by thermal drift in sensitivity.
