Hall-effect latch sensors

  • 22-Jul-2010 01:59 EDT

Melexis’ MLX92211 is a second-generation automotive Hall-Effect latch sensor. The successor of Melexis’ USx88x series, the MLX92211 is designed with a new platform. It features robustness for the more stringent automotive requirements, such as electrical power steering (EPS), window lifters/sunroof, seat adjusters, wipers, or motor commutation. The MLX92211 core is based on a high-voltage submicron process suited to handle low- and high-operating voltage from 2.7 to 24 V, as well as low- and high-operating temperature from -40 to +150°C (-40 to +302°F). With latching magnetic behavior, the open-drain output is switched on and off by applying south and north magnetic field perpendicularly to the package top side, which is typically the case with rotary applications using on-shaft multipoles ring magnet. Because the MLX92211 is designed for automotive applications, the device integrates all protections required when using integrated or remote sensors.
