3058

The A3046EU/LU, A3056EU/LU, and A3058EU/LU Hall effect

gear-tooth sensors are monolithic integrated circuits that switch in

response to differential magnetic fields created by ferrous targets.

These devices are ideal for use in gear-tooth-based speed, position,

and timing applications and operate down to zero rpm over a wide

range of air gaps and temperatures. When combined with a back-

biasing magnet and proper assembly techniques, devices can be

configured to give 50% duty cycle or to switch on either leading,

trailing, or both edges of a passing gear tooth or slot.

The six devices differ only in their magnetic switching values and

operating temperature ranges. The low hysteresis of the A3046/56EU

and A3046/56LU makes them perfectly suited for ABS (anti-lock brake

system) or speed sensing applications where maintaining large air

gaps is important. The A3046EU/LU features improved switch point

stability with temperature over the A3056EU/LU. The high hysteresis

of the A3058EU and A3058LU, with their excellent temperature

stability, makes them especially suited to ignition timing applications

where switch-point accuracy (and latching requirements) is extremely

important.
