Description
The UGS3059KA and UGN/UGS3060KA
ac-coupled Hall-effect gear-tooth sensors are monolithic integrated circuits
that switch in response to changing differential magnetic fields created by
moving ferrous targets. These devices are ideal for use in non-zero-speed,
gear-tooth-based speed, position, and timing applications such as in
anti-lock braking systems, transmissions, and crankshafts.
Both devices, when coupled with a
back-biasing magnet, can be configured to turn ON or OFF with the leading or
trailing edge of a gear-tooth or slot. Changes in fields on the magnet face
caused by a moving ferrous mass are sensed by two integrated Hall transducers
and are differentially amplified by on-chip electronics. This differential
sensing design provides immunity to radial vibration within the devices'
operating air gaps. Steady-state magnet and system offsets are eliminated
using an on-chip differential band-pass filter. This filter also provides
relative immunity to interference from RF and electromagnetic sources. The
on-chip temperature compensation and Schmitt trigger circuitry minimizes
shifts in effective working air gaps and switch points over temperature,
allowing operation to low frequencies over a wide range of air gaps and
temperatures.
Each Hall-effect digital Integrated
circuit includes a voltage regulator, two quadratic Hall-effect sensing
elements, temperature compensating circuitry, a low-level amplifier,
band-pass filter, Schmitt trigger, and an open-collector output driver. The
on-board regulator permits operation with supply voltages of 4.5 to 24 volts.
The output stage can easily switch 20 mA over the full frequency response
range of the sensor and is compatible with bipolar and MOS logic circuits.
