The A1220, A1221, A1222, and A1223 are Hall-effect sensor ICs designed for high-temperature and stress-resistant applications.

Key Features:

These devices offer:

  • Symmetrical latch switch points
  • Resistant to physical stress and superior temperature stability
  • Output short-circuit protection and operation from unregulated supply down to 3 V
  • Reverse-battery protection and solid-state reliability
  • Small package sizes (3-pin SOT23W and 3-pin SIP)

Applications:

Typical applications include:

  • Automotive
  • Industrial motor encoders
  • Power closures/actuators
  • Commutation/index
  • Electronic power steering sensing
  • Seat/windows/sunroof
  • BLDC motors
  • Fan motors
  • Trunk/door/liftgate motors
