MLX90513 Inductive position sensor interface IC Datasheet
■An inductive position sensor is used for absolute rotary and linear motion/position sensing in automotive and industrial applications. The MLX90513 is designed to control an inductive sensor to process the captured analog sensor signals and to provide 3 output modes. The MLX90513 supports (fast) SENT frames encoded according to all formats of the SENT standard, including Secure Sensor format, as well as SPC frames. For SENT/SPC the circuit delivers enhanced serial messages providing error codes and user- defined values. The MLX90513 can also be configured to output a PWM (Pulse Width Modulated) signal and an analog ratio-metric output is also supported. The inductive sensor operation is based on the inductive coupling between a transmitting coil, the target and three receiver coils. The on-chip LC oscillator generates an electromagnetic field together with the transmitting coil. This electromagnetic field induces a target (rotor) angle dependent voltage in the three receiving coils. These three signals are captured and processed by the MLX90513 internal signal processing units. The receiving coils are arranged in a fixed staggered position to each other depending on the number of poles of the metallic target (rotor) above the coils. Typically, the coils are realized as printed circuit board tracks.
