MLX91216 - 250 kHz IMC-Hall® current sensor with diagnostics

The MLX91216 is part of the Gen2.5 high speed current sensor portfolio, targeting primarily inverter/converter applications as well as redundant monitoring of battery-management system (BMS). With the IMC-Hall® technology - using a flexible U-shield for crosstalk immunity - currents can be measured in the ranges of 200A to 2000A. The magnetic flux density inside the shield is amplified by the on-chip Integrated Magnetic Concentrator (IMC), then measured with embedded Hall-effect technology and amplified to a 5V full-scale ratiometric and fast analog output. The novel CMOS Hall-effect sensor is offered with different factory trimmed offset, sensitivity and filtering settings, but is customer programmable using the Melexis programming equipment PTC-04.

  • Measurement range
           -MLX91216 ACH versions (High field): for current from 200 to 600 A
           -MLX91216 ACV versions (Very high field): for current from 400 to 1200 A
           -MLX91216 ACX versions (eXtra high field): for current from 800 to 2000 A Programmable gain, offset, filtering, clamping and more
  • 48bit unique ID for traceability
  • AEC-Q100 Grade 0 qualified
  • SOIC8 (DC) package, RoHS, MSL-3

The SOIC8 package and U-shield allow for vertical stacking and easy mechanical assembly, lower weight and true surface mount manufacturing processes. The IMC-Hall® technology lends itself very well to vibration-rich environments such as those witnessed when electrification moves closer to e.g. vibrant transmission environments.
