Linear position sensor MLX90378

contactlessmagneticPWM

The MLX90378 is a monolithic magnetic position processor IC designed for 3D motion applications (e.g. joysticks). Top features ISO26262 ASIL-C Safety Element out-of-Context (SEooC) Input/gateway pin for external measurement 2-axis joystick measurement Product description The MLX90378 is a third generation Triaxis® position sensor IC. Thanks to an integrated magnetic concentrator (IMC) on its surface, the monolithic device senses, in a contactless fashion, the three spatial components (i.e. Bx, By and Bz) of the applied magnetic field allowing for the determination of 3D or joystick motion. The MLX90378 supports both ball and socket as well as gimbal configurations. The ball and socket configuration is distinguished by the fact that the rotation point of the magnet is above the plane of the sensor while the gimbal configuration has both axes in the same plane as the sensor. Thanks to the multi-point calibration inside the sensor both configurations can be accurately measured. The MLX90378 is offered as an ASIL-C SEooC (Safety Element out of Context - ISO 26262) component. Contact Melexis to obtain a copy of the MLX90378 safety manual which details the relevant system integration requirements. For applications requiring redundant sensing the MLX90378 is also available in a dual die (fully redundant) TSSOP-16 package. The output transfer characteristic is fully programmable and offers both SENT or dual PWM outputs. The SENT output supports two angles (forward/backward and left/right) in a single SENT frame or can be configured to give the X, Y, and Z magnetic signals via fast channel multiplexing.
