Back-bias solution for position sensing applications
Melexis’ Latch & Switch sensor ICs use an innovative magnetic technology that allows the measurement of the lateral magnetic flux component. As a result of the inclusion of IMC technology, simple wheel speed sensing on motorcycles can now be performed using a single two-wire switch sensor IC with an integrated capacitor (MLX92242 IC or MLX92241 IC) and a traditional magnet. This approach uses the lateral field rather than the previous method of using the perpendicular field, thus vastly simplifying the designer’s task.

Magnetic Latch Switch: Experience matters
25+ years in Latch & Switch has given Melexis a unique view of market needs. Decisions taken in 1993 to focus on CMOS technology and TSOT packaging are just as valid today as they were then.
Understanding Latch & Switch evaluation board for MLX922xx products
In this video, Thomas Strauven, Applications Engineer for Latch & Switch, demonstrates the functionalities of the Melexis programmable Latch & Switch demo board for MLX922xx IC products. This demo board is ideal for low volume testing and quick evaluation.
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.
