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

Product description

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.

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.

application Main DCDC thumbnail

main DCDC

The DC/DC converter produces low voltage DC electricity (e.g. 12 V, 14 V, 24 V) from the high voltage battery (e.g. 48 V up to 800 V) to supply the boardnet and charge the low voltage battery.
