Product description
The MLX90425 is a magnetic position sensor designed for use in cost-sensitive automotive applications including powertrain actuators, pedal positioning, fuel level gauges and transmission systems, though also suitable for industrial implementations. MLX9042x devices have superior capabilities in terms of functional safety, Absolute Maximum Ratings (AMR) and electromagnetic compliance (EMC) characteristics. They also support operating temperature up to 160 °C
The MLX90425 is pin-to-pin compatible with the previous generations of Triaxis® position sensor ICs
The MLX90425 is a monolithic magnetic position sensor IC. It consists of a Triaxis® Hall magnetic front end, an analog to digital signal conditioner, a DSP for advanced signal processing and a programmable output stage driver.
The MLX90425 is sensitive to the differential magnetic field in the Z-axis. This allows the MLX90425 with the correct magnetic circuit to decode the absolute position of a rotating on-axis magnet above or below the sensor (e.g. rotary position from 0 to 360 Degrees). It enables the design of non-contacting position sensors that are frequently required for both automotive and industrial applications.
