Hi Jim! It's the Melexis HB:

Digi-Key - MLX91205KDC-HB-ND (Manufacturer - MLX91205KDC-HB)

It can be had cheaper at other places than Digikey, though.

Basically, the magnetic field through the sensor (from left to right or vice versa corresponds to a voltage on the output pin of the sensor. The current through the bus bar (from top to bottom) makes a magnetic field from left to right (or whatever. haha) The further away the sensor is from the magnetic field, the less sensitive the output is.
