Melexis launches dual-die sensors and latches

Melexis, the Belgian auto IC specialist,  has launched a range of  dual-die magnetic latch and switch sensors aimed at automotive applications like transmission, power steering, braking and locks/latches, represent a major advance in magnetic sensing technology.

Melexis, the Belgian auto IC specialist,  has launched a range of  dual-die magnetic latch and switch sensors aimed at automotive applications like transmission, power steering, braking and locks/latches, represent a major advance in magnetic sensing technology.

By integrating two ICs into a single package, Melexis can provide the redundant operation that is crucial to meet the reliability requirements of the automotive market.

It also means that a significant improvement can be made in terms of accuracy – as the sensitive points are closer together than they would be with discrete devices housed in separate packages.

The first products that are available with the dual-die packaging concept are the MLX92292 and MLX92232.

The MLX92232 is a second-generation programmable Hall effect sensor designed using state-of-the-art mixed signal CMOS technology. This dual die device incorporates a voltage regulator, Hall sensing functionality (with advanced offset cancellation system) and an open-drain output driver, all in a single package. It is supplied in a 4-pin through-hole format.

This is complemented by the 3-wire μPower Melexis MLX92292, which comes in an 8-pin surface mount SO-8 package. It delivers the expected switch functionality but, unlike existing products on the market, can determine the presence of magnetic fields that are lateral, not just orthogonal, to it.

It supports ASIL B functional safety (in accordance with ISO 26262), with an array of built-in diagnostic mechanisms providing highly reliable operation in automotive applications.

Both can be pre-programmed to meet specific application requirements. In addition, OEM customers can benefit from the flexibility of factory programming to give them complete in-system optimization at their own production lines.

The programming capability 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).
