Hall effect integrated circuit current sensor MLX91217

PCBDCAC

The MLX91217 is part of the Gen 2.5 high speed current sensor IC portfolio, targeting primarily inverter/converter applications. With the Conventional Hall technology - using an external ferromagnetic core for signal concentration - Product description The MLX91217 is part of the Gen 2.5 high speed current sensor IC portfolio, targeting primarily inverter/converter applications. With the Conventional Hall technology - using an external ferromagnetic core for signal concentration - currents can be measured in the range of ±50 A to ±5000 A. The magnetic flux density inside the airgap of the core is measured with embedded Hall-effect technology and amplified to a 5 V 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 are customer programmable using the Melexis programming equipment PTC-04. The main changes over the Gen 2 MLX91209 are: Higher accuracy Thermal offset drift of ±5 mV (50% improvement) Thermal sensitivity drift of ±1% (33% improvement) Improved diagnostics Broken Wire detection Programmable output clamping levels Extended on-chip filtering The SIP4-VA package allows for insertion of the sensing elements into tight slots of the core, and several Trim&Form options of the sensor leads provide designers with higher flexibility for mechanical integration & assembly. The following factory trim variants are available: MLX91217LVA-ACA-000 with 10 mV/mT sensitivity and bipolar output around 2.5 V MLX91217LVA-ACA-003 with 9 mV/mT sensitivity and bipolar output around 2.5 V MLX91217LVA-ACA-005 with 13 mV/mT sensitivity and bipolar output around 2.5 V
