MLX90424 - Triaxis® mainstream linear SFI position sensor with wake-up switch function
|
The MLX90424 is a magnetic position sensor IC designed for linear movement applications integrating a wake up switch function. It leverages the combined capabilities of three distinct dies: two MLX90423 Triaxis® Hall magnetic front ends and one MLX92292 Latch and Switch. The MLX90424 accurately detects the three components of magnetic flux density (Bx, By, Bz). |
This enables precise measurement of linear displacement, making it ideal for applications where non-contact position sensing is essential. The MLX90424 offers flexible output options, including PWM, and SENT frames encoded in a Secure Sensor format. This ensures compatibility with various systems and simplifies integration. |
