MLX91217 is for a conventional Hall set-up – it comes in a slim pin-thru package for integration into conventional Hall-effect measuring rings (see diagram) . Various lead shapes make it compatible with different mounting styles including surface-mount.

MLX91216 is the unusual one, employing Melexis’ proprietary ‘integrated magneto concentrator’ (IMC) – which “requires no external ferromagnetic concentrator ring”, said the firm – see diagram. “The SOIC8 package and U-shield allow for vertical stacking and easy mechanical assembly, lower weight and true surface mount manufacturing processes.”
