The MLX91205 is a single axis IMC-Hall® integrated current sensor featuring Triaxis® technology. It produces an analog linear, ratio-metric output voltage proportional to the applied magnetic field parallel with the chip surface.
The circuit is fabricated using a standard complementary metal oxide semiconductor (CMOS) process, with the addition of an integrated magnetic concentrator (IMC-Hall®). This ferromagnetic layer amplifies the magnetic field and concentrates it on the Hall elements. Therefore, the circuit features very high magnetic sensitivity, low offset and low noise. The MLX91205 is ideally suited for current sensing in automotive and industrial environments.
Two different factory programmable product versions with different magnetic ranges are available:

  • MLX91205 LB: Low magnetic field (10mT Version)
  • MLX91205 HB: High magnetic field (25mT Version)
