Melexis MLX92362/1 Hall Based SOI Floating Switch
Isolated output programmable Hall Effect Latch/Switch/Omnipolar Switch
The Melexis MLX92362/1 is a revolutionary Hall switch providing better assembly yield and reliability in fluid level measurements. With Its isolated floating output, the MLX92361 only requires power to directly drive the load. The MLX92362/1 is a monolithic sensor IC sensitive to normal or lateral magnetic field. It has two output pins, OUTA and OUTB, which are connected to an electrically isolated switch.
The MLX92362/1 can be programmed to output direct or inverted signal from one of the two sensitive axes – X(Y) or Z. The signal available on the output pins is the result of a comparison between the applied magnetic field and the pre-programmed magnetic thresholds BOP and BRP for the selected sensitive axis.
The MLX92362/1 can be programmed to act as magnetic latch or unipolar switch or omnipolar switch.
The MLX92362/1 can be used as general replacement of reed switches having the advantage of solid-state reliability.
Note that a series of ICs can be connected in a single module, and synchronized via the same 3-wire interface thanks to the built-in daisy-chain function.
For development programming, the EVB92662 is available. For mass-production programming, the MLX92362 is compatible with the PTC04 (DB-HALL06).

Evaluation Board for MLX92362 Latch & Switch
The EVB2 for Latch & Switch (LatchSwitchEVB2) is a compact and versatile board to program and control the MLX92362. It connets via USB. A Graphical User Interface (GUI) is provided.
The EVB is an evaluation board meant for lab and prototyping evaluation. It can also be used as a demonstator.
The Latch and Switch EVB2 can also be used for small volume programming, when the costs for acquiring the Melexis Programmable Toolbox (PTC-04) is too high for the project. For end of line programing (mass production), the Melexis PTC-04 should be used.
