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.
The two devices provide a choice of operating temperature ranges.
Both devices are packaged in a 5-pin plastic SIP, with an option of
trimmed, formed pins for horizontal mounting. The UGN/UGS3060KA
offers a Pb (lead) free version, with 100% matte tin leadframe plating.
