3-wire ASIL B Hall sensor IC with lateral sensing - MLX92292
Product description
The MLX92292 delivers switch and latch 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 latch/switch IC is able to support ASIL B safety integrity level (in accordance with ISO26262), with an array of built-in diagnostic mechanisms available.
Flexibility is a key attribute of the MLX92292. OEM customers can choose 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.
Housed in 3-lead TSOT or TO92 package formats, with an operating voltage range encompassing 3.3 V to 18 V, the MLX92292’s extremely low power consumption (typically drawing just 7µA) makes it highly suitable for battery-powered operation. This will prove advantageous in circumstances where the vehicle’s engine may not be turned on, as it places no significant drain on the battery resource. As sleep time is a programmable parameter.

Lateral sensing with integrated IMC for DC/BLDC motor applications
As brushless DC (BLDC) motors become an increasingly popular choice for many applications including blowers, cooling fans and pumps, more sophisticated control is required. By integrating an IMC into products, such as the MLX92211 IC, surface mount sensing is available, thereby simplifying the production process and reducing the space required.
Magnetic Latch & Switch sensor IC for high demanding safety applications
The MLX92292 Latch & Switch sensor IC represents a whole new way of sensing. It's the first chip designed with the Triaxis® technology (lateral sensing) and the very first switch on the market with ASIL-B readiness, combined with MicroPower.
Programming MLX92292 Latch & Switch IC explained
The MLX92292 IC is Melexis’ third generation programmable Latch & Switch sensor IC that can be programmed at Melexis, but with the ability to program it within the customer’s application. This means that the sensor IC is ideal for rapid prototyping or for real end-of-line programming. During this video, Thomas Strauven, Applications Engineer for Latch & Switch, explains how to program the MLX92292 sensor IC that is assembled inside the module and trimming of the thresholds will be done in a final stage.
