Melexis unveils a variant of the MLX92211, a 3-wire Hall-effect latch. This new device is designed for lateral magnetic position sensing, with high ESD protection and a high output current limit. This latest addition enables motor miniaturization by providing enhanced integration and cost-effective performance, ideal for automotive compact motors used in applications such as seat motors, sunroofs and thermal expansion valves.
Across the automotive sector, there is a rising demand for smaller, slimmer motor modules that do not compromise on robustness or diagnostics. This is especially critical in seat actuators, where multiple motors must be integrated into compact assemblies without sacrificing adjustability, comfort, or compliance with safety requirements. OEMs are under constant pressure to maximize cabin space and reduce vehicle weight, all while enhancing in-cabin functionality and supporting automated production. The same constraints apply to other areas of the vehicle like sunroofs and thermal valves, where reduced module height and surface-mount compatibility enable slimmer mechanical designs and more flexible integration.
The MLX92211 IMC addresses these demands head-on with an integrated magnetic concentrator (IMC) that enables lateral sensing in a surface-mount device (SMD) TSOT-3L package – eliminating the need for through-hole components and aligning with modern automated assembly processes. The result is a reduced motor height, improved packaging flexibility, and optimized manufacturing workflows.
Melexis’ newest MLX92211 IMC variant is built on the proven MLX92211 platform, delivering an optimized lateral-sensing option. The single-package device integrates a voltage regulator (2.7 to 24V operating range), a Hall effect sensor with advanced offset cancellation, and an open-drain output driver. The magnetic core’s enhanced offset cancellation system facilitates faster, more accurate, and robust processing, irrespective of temperature and stress, and includes a negative temperature coefficient to counteract the natural weakening of magnets at high temperatures.
