Automobiles want smaller motors that work properly and are protected. A brand new sensor can assist make motors smaller, stronger, and simpler to construct into automobiles.
Automakers want smaller, slimmer motor modules that don’t compromise on efficiency, security, or reliability. In seat actuators, sunroofs, and thermal enlargement valves, a number of motors should match into tight areas with out decreasing adjustability, consolation, or security compliance. OEMs are below fixed stress to cut back automobile weight, improve cabin house, enhance in-cabin options, and assist automated manufacturing strategies.
The MLX92211, Built-in Magnetic Concentrator (IMC) from Melexis solves these challenges by integrating a magnetic concentrator in a surface-mount TSOT-3L package deal. This eliminates through-hole elements and permits decrease motor peak, higher packaging flexibility, and simpler automated meeting. The result’s compact motors and actuators that meet strict automotive measurement, efficiency, and security necessities.
Designed for lateral magnetic place sensing, the IMC supplies robust ESD safety and a excessive output present restrict, enabling dependable operation in harsh automotive environments. It helps each 3-wire and 2-wire setups, with a 30 mA present restrict that simply handles steady present wants, comparable to these in seat motors. Its superior offset cancellation ensures quick, correct, and secure sensing even when temperature and mechanical stress differ.
With a large working voltage vary, built-in voltage regulator, and open-drain output driver, the IMC supplies constant and dependable sensor efficiency. Its damaging temperature coefficient helps keep sensitivity regardless of the pure lack of magnet power at larger temperatures.
“With the MLX92211 IMC, we’ve responded on to the automotive business’s demand for extra compact, application-optimized motor latch sensors,” stated Minko Daskalov, Product Line Supervisor at Melexis. “By enabling lateral magnetic sensing in a sturdy and cost-effective format, it permits engineers to cut back actuator peak, improve motor integration inside tight areas – all whereas sustaining the efficiency and safety ranges anticipated in trendy automotive environments.”
The sensor additionally gives 8 kV ESD safety, automated output shut-off with self-recovery, and purposeful security readiness (ASIL A), giving designers the boldness wanted for safety-critical automotive purposes.
