Tessenderlo, Belgium, December 2, 2022 - Melexis, a global microelectronics engineering company, today announced the release of the MLX92352, a versatile programmable 3-axis latch and switch chip for relative position and velocity sensing applications.The device features a flexible magnetic design that supports dual outputs and The outputs can be set to velocity, pulse or direction, regardless of pitch. With its excellent EMC and ESD performance, this PCB-free device saves space and total module cost for automotive and industrial applications.
The MLX92351 (pre-programmed) and MLX92352 (programmable) are quadrature output devices that precisely locate the speed and direction of the motor system. 90° phase shift between the two outputs makes the devices independent of pitch and air gap for easier magnetic design. for greater flexibility. Magnetic thresholds range from ±0.5mT to ±40mT, enabling industry-leading magnetic accuracy. Using Melexis' silicon on insulator (SOI) technology, this family of magnetic latch and switch chips offers outstanding performance: 15kV HBM ESD, 8kV system ESD and high EMC robustness. This PCB-free solution saves space and cost, and the single-chip solution for DC motor counting simplifies the design. The MLX92352 and MLX92351 operate over a voltage range of 2.7 V to 60 V at a junction temperature of 175°C. Equally important, a last state feedback function at startup ensures continuous and stable motor system operation.
