General Description
Melexis has made a major advance in magnetic sensing technology that will have widespread implications for
modern automobile design the MLX92292 - effectively represents a whole new way of sensing. This device
delivers switch functions, but unlike existing products on the market it can determine the presence of
magnetic fields that are lateral, not just orthogonal, to it. The uniqueness of this offering is taken further by the
fact that the MLX92292 switch is supporting an ASIL B safety integrity level (in accordance with ISO 26262),
with an array of built-in diagnostic mechanisms available.
Flexibility is a key attribute of the MLX92292. OEM customers can chose straightforward pre-programmed
units, or alternatively they can benefit from the end-of-line (EoL) programming capacity. Through this each
device may be configured (via its output pin) during the OEM production process, so system optimization is
fully realized. The programming facility also enables setting of both magnetic operating points to small
increments across a range spanning -90mT to +90mT (-40mT to +40mT for lateral sensing versions).
The MLX92292 can be specified with standard orthogonal sensitivity or the lateral sensitivity option. The
upshot of lateral sensitivity being that there is potential to replace multiple devices with a single surface
mount unit, thereby saving valuable board space and lowering bill-of-materials costs. This stems directly from
Melexis’ proprietary Integrated Magnetic Concentrator (IMC™) technology, which enables substantial
heightening of signal-to-noise ratios in magnetic field measurement. In addition, the capacity of this
technology to sense laterally allows lower profile system implementations, as the magnet can move alongside
the device rather than having to be above it.
Safeguarding the MLX92292 are reverse supply voltage, thermal, electro-static discharge (ESD) and over-
voltage protections, plus Under-Voltage Reset features. With the capacity to deal with a 40V load dump, it
can be connected directly to the vehicle battery. In order to achieve ASIL B compliance, numerous
diagnostic/monitoring functions have been incorporated, including Hall sensor and analog frontend
diagnostics. The device comprises a full set of programmable reporting features, giving it compatibility with
any existing electronic control unit (ECU) interface. Only the normal application pins are required for this -
without need of additional diagnostic pins and thus simplifying the design concept considerably.
