3D Triaxis dual latch & switch (pre-programmed) - MLX92351

Product description

The MLX92351 is a monolithic sensor IC sensitive to magnetic field applied to X, Y and Z axes of the package. It provides ultimate configurability with its 90 degrees phase shift for a pitch independent magnetic design. Any axes combination ZX, ZY, XY, XX, YY or ZZ on its open drain outputs is possible.

The device enables PCB-less module designs to save on your total cost of ownership without the need of external passive components. The MLX92351withstands 15kV HBM, 8kV System ESD and it has high EMC robustness.

The MLX92351 can be programmed to act as magnetic latch, unipolar switch or omni-polar switch. The magnetic thresholds BOP and BRP can be programmed independently for each axis. Furthermore, the MLX92351 processes digitally the magnetic signal and outputs Speed, Direction or Pulse.

The MLX92351 can be used to detect the rotation speed and direction of a ring magnet when configured as a dual magnetic latch. It can also switch on two independent magnet positions for complex position designs.

Customers can benefit from the end of line (EoL) programming capability of the MLX92352 to trim mechanical tolerances away or alternatively choose a pre-programmed MLX92351 device.

Applications:

  • Linear speed & direction control: power liftgate, closures with anti-pinch
  • Incremental rotary encoding: cadence sensor for e-bikes, DC motor indexing, fan & pump motors
  • Dual linear position detection: piston, lever, stalks, valves
  • Angular position detection: knobs, jog wheels
