Automotive systems are becoming more complex due to electrification, autonomy, and advanced driver-assistance systems (ADAS), increasing the need for dual-channel position sensing to deliver accurate torque and angle measurements. Traditionally, this required combining two single-channel ICs or using magnetic sensors, but these approaches can add cost and complexity. Cars are getting more advanced. One sensor can track two positions at once, make systems simpler, and give accurate steering and torque control. Cars are getting more advanced.

Tessenderlo-Ham, Belgium – 9
October 2025 – Melexis announces the MLX90514, a dual-input inductive sensor
integrated circuit (IC). The novel device simultaneously processes signals from
two sets of coils to compute differential or vernier angles on-chip. This
sensor is designed for next-generation automotive applications, particularly in
systems such as steering torque feedback, steering angle sensing, or steering
rack motor control (including steer-by-wire implementations).
