Melexis Launches Industry-First Dual-Input Inductive Sensor MLX90514, Revolutionizing Automotive Steering System Design

Global microelectronics engineering company Melexis has announced the launch of its first dual-input inductive sensor chip, the MLX90514. This product can simultaneously process signals from two coil sets and perform on-chip calculations for differential or vernier angles, providing a highly integrated solution for next-generation automotive steering torque feedback, steering angle detection, and steer-by-wire systems.

With the rapid development of vehicle electrification, autonomous driving, and ADAS technologies, the demand for dual-channel position sensing in critical control units like steering systems continues to grow. Traditional solutions typically use two separate single-channel chips or magnetic sensors, whereas the MLX90514 significantly reduces system complexity and component costs through high integration. Its on-chip computation capability effectively alleviates the processing burden on the main control unit, enabling more compact and efficient sensor design.

The MLX90514 offers flexible interface configuration: standalone modules support SENT, SPC, and PWM interfaces, while embedded modules utilize SPI interface. Its SENT/SPC output supports payloads of up to 24 bits, enabling synchronous transmission of two 12-bit channel data to meet stringent requirements for high-precision torque and angle measurement.

As Melexis's first dual-inductive Application-Specific Standard Product (ASSP), the MLX90514 achieves functionalities that previously required multi-chip solutions in a single chip. This not only simplifies system architecture but also enhances reliability, providing a more cost-effective sensing solution for electric vehicles and emerging mobility applications.
