Top Features

Packaging

  • GMR technology senses at near or far air gap for optimal design-in flexibility
  • Integrated EMC circuit protects against harsh supply line transients eliminating the need for a large bypass capacitor and twisted pair harness
  • System compensation for vibration, mechanical shifts, and thermal gradients to ease controller burden and increase signal reliability
  • Test pin access for system characterization within application environment
  • Speed or Speed and Direction output protocol allows single qualification to cover multiple applications

The ATS19581 is provided in a single overmolded lead (Pb) free 3-pin SIP package (ST) with tin leadframe plating. The ST package includes a GMR IC, a magnet, and the EMC circuit, including the bypass capacitor.
