Melexis MLX92361 Hall-Based SOI Floating Switch

Melexis MLX92361 Hall-Based SOI Floating Switch provides better assembly yield and reliability in fluid level measurements. With its isolated floating output, the MLX92361 only requires power to drive the load directly. The MLX92361 is a monolithic sensor IC sensitive to a typical or lateral magnetic field. It has two output pins, OUTA and OUTB, connected to an electrically isolated switch. The Melexis MLX92361 can be pre-programmed to output a 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 MLX92361 can be pre-programmed to act as a magnetic latch, unipolar, or omnipolar switch.

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.
