Inductive position sensor interface IC (Analog/PWM/SENT/SPC) - MLX90513
Product description
The MLX90513 is an inductive position sensor interface is used for absolute rotary and linear motion/position sensing in automotive and industrial applications. It is designed to control an inductive sensor (coils) and to process the captured analog signals. It supports 4 output modes: SENT/SPC (Short PWM Code), PWM and analog.
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 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.
For engineering development, you can utilize the EVB90513 evaluation kit. When it comes to production, both engineering and mass production, the MLX90513 is fully compatible with the PTC-04 (DB-HALL06).
Application examples:
